Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey, should be less than the compliance level in each frequency range. Interference may occur in the vicinity of equipment marked with the following symbol: Note 1) At 80MHz and 800MHz, the higher frequency range applies. Note 2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people. Field strengths from fixed transmitters, such as base stations for radio, (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcasts cannot be predicted with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength, in the location in which the Ultrasound System is used, exceeds the applicable RF compliance level above, the Ultrasound System should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the Ultrasound System or using a shielded location with a higher RF shielding effectiveness and filter attenuation. IOver the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.

[Page 30] 1 - 16 HS70A Service Manual ▐ Recommended Separation Distances between This Product and RF Communications Equipment This product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of this product can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and this product. These distances are recommended below, according to the maximum output power of the communications equipment.

ESD caused by discharging of electric charge build-up on insulated surfaces or persons. 2. RF energy from RF transmitting equipment such as portable phones, hand-held radios, wireless devices, commercial radio and TV, and so on. 3. Conducted interference on power lines or connected cables caused by other equipment, such as switching power supplies, electrical controls, and natural phenomena such as lightning. A medical device can either generate or receive electromagnetic interference. The EMC standards describe tests for both emitted and received interference. Samsung Medison ultrasound systems do not generate interference in excess of the referenced standards. The Ultrasound System is designed to receive signals at radio frequency and is therefore

[Page 33] Chapter 1 Safety 1 - 19 susceptible to interference generated by RF energy sources. Examples of other sources of interference are medical devices, information technology products, and radio and television transmission towers. Tracing the source of radiated interference can be a difficult task. Customers should consider the following in an attempt to locate the source: - Is the interference intermittent or constant? - Does the interference show up only with one transducer operating at the same frequency or with several transducers? - Do two different transducers operating at the same frequency have the same problem? - Is the interference present if the system is moved to a different location in the facility? The answers to these questions will help to determine if the problem resides with the system or the scanning environment. After you answer this question, contact your local Samsung Medison customer service representative.

[Page 38] 1 - 24 HS70A Service Manual Biological Safety For safety instructions concerning probes and biopsies, refer to HS70A User Manual. ■ Ultrasound waves may have damaging effects on cells and, therefore, may be harmful to the patient. If there is no medical benefit, minimize the exposure time and maintain the ultrasound wave output level at low. Please refer to the ALARA principle. ■ Do not use the system if an error message appears on the video display indicating that a hazardous condition exists. Note the error code, turn off the WARNING power to the system, and call Samsung Medison customer service department. ■ Do not use a system that exhibits erratic or inconsistent functioning. Discontinuities in the scanning sequence are indicative of a hardware failure that should be corrected before use. ■ The system limits the maximum contact temperature to 43 degrees Celsius, and the ultrasonic wave output observes American FDA regulations. ALARA Principle Guidance for the use of diagnostic ultrasound is defined by the ”( A s L ow A s R easonably A chievable) (ALARA) principle. The decision as to what is reasonable has been left to the judgment and insight of qualified personnel. No set of rules can be formulated that would be sufficiently complete to dictate the correct response to every circumstance. By keeping ultrasound exposure as low as possible, while obtaining diagnostic images, users can minimize ultrasonic bioeffects. Since the threshold for diagnostic ultrasound bioeffects is undetermined, it is the sonographer’s responsibility to control the total energy transmitted into the patient. The sonographer must reconcile exposure time with diagnostic image quality. To ensure diagnostic image quality and limit exposure time, the Ultrasound System provides controls that can be manipulated during the exam to optimize the results. The ability of the user to abide by the ALARA principle is important. Advances in diagnostic ultrasound, not only in the technology but also in its applications, have resulted in the need for increased and improved information to guide the user. The output indices are designed to provide that important information. There are a number of variables, which affect the way in which the output display indices can be used to implement the ALARA principle. These variables include mass, body size, location of the bone relative to the focal point, attenuation in the body, and ultrasound exposure time. Exposure time is an especially useful variable, because the user controls it. The ability to limit the index values over time supports the ALARA principle.

[Page 39] Chapter 1 Safety 1 - 25 ▐ Applying ALARA The system imaging mode used depends upon the information needed. 2D-mode and M-mode imaging provide anatomical information, while Doppler, Power, and Color imaging provide information about blood flow. Scanned modes, like 2D-mode, Power, or Color, disperse or scatter the ultrasonic energy over an area, while an unscanned mode, like M-mode or Doppler, concentrate the ultrasonic energy. Understanding the nature of the imaging mode being used allows the sonographer to apply the ALARA principle with informed judgment. The probe frequency, system set-up values, scanning techniques, and operator experience aid the sonographer in meeting the ALARA principle. The decision as to the amount of acoustic output is, in the final analysis, up to the system operator. This decision must be based on the following factors: type of patient, type of exam, patient history, ease or difficulty of obtaining diagnostically useful information, and the potential localized heating of the patient due to probe surface temperatures. Prudent use of the system occurs when patient exposure is limited to the lowest index reading for the shortest amount of time necessary to achieve acceptable diagnostic results. Although a high index reading does not mean that a biological effect is actually occurring, it should be taken seriously. Every effort should be made to reduce the possible effects of a high index reading. Limiting exposure time is an effective way to accomplish this goal. There are several system controls that the operator can use to adjust the image quality and limit the acoustic intensity. These controls are related to the techniques that an operator might use to implement ALARA and can be divided into three categories: direct, indirect, and receiver control. ▐ Direct Controls Application selection and the output intensity control directly affect acoustic intensity. There are different ranges of allowable intensity or output depending on your selection. Selecting the correct range of acoustic intensity for the application is one of the first things required during any exam. For example, peripheral vascular intensity levels are not recommended for fetal exams. Some systems automatically select the proper range for a particular procedure, while others require manual selection. Ultimately, the user bears the responsibility for proper clinical use. Samsung Medison systems provide both automatic and user-definable settings. Output has direct impact on acoustic intensity. Once the application has been established, the output control can be used to increase or decrease the output intensity. The output control allows you to select intensity levels less than the defined maximum. Prudent use dictates that you select the lowest output intensity consistent with good image quality. ▐ Indirect Controls The indirect controls are those that have an indirect effect on acoustic intensity. These controls affect

[Page 40] 1 - 26 HS70A Service Manual imaging mode, pulse repetition frequency, focus depth, pulse length, and probe selection. The choice of imaging mode determines the nature of the ultrasound beam. 2D-mode is a scanning mode, Doppler is a stationary or unscanned mode. A stationary ultrasound beam concentrates energy on a single location. A moving or scanned ultrasound beam disperses the energy over a wide area and the beam is only concentrated on a given area for a fraction of the time that is necessary in unscanned mode. Pulse repetition frequency or rate refers to the number of ultrasound bursts of energy over a specific period of time. The higher the pulse repetition frequency, the more pulses of energy in a given period of time. Several controls affect pulse repetition frequency: focal depth, display depth, sample volume depth, color sensitivity, number of focal zones, and sector width controls. The focus of the ultrasound beam affects the image resolution. To maintain or increase resolution at a different focus requires a variation of output over the focal zone. This variation of output is a function of system optimization. Different exams require different focal depths. Setting the focus to the proper depth improves the resolution of the structure of interest. Pulse length is the time during which the ultrasonic burst is turned on. The longer the pulse, the greater the time-average intensity value. The greater the time-average intensity, the greater the likelihood of temperature increase and cavitations. Pulse length, burst length or pulse duration is the output pulse duration in pulsed Doppler. Increasing the Doppler sample volume, increases the pulse length. Probe selection affects intensity indirectly. Tissue attenuation changes with frequency. The higher the probe operating frequency, the greater the attenuation of the ultrasonic energy. Higher probe operating frequencies require higher output intensity to scan at an increased depth. To scan deeper at the same output intensity, a lower probe frequency is required. Using more gain and output beyond a point, without corresponding increases in image quality, can mean that a lower frequency probe is needed.  Receiver Controls Receiver controls are used by the operator to improve image quality. These controls have no effect on output. Receiver controls only affect how the ultrasound echo is received. These controls include gain, TGC, dynamic range, and image processing. The important thing to remember, relative to output, is that receiver controls should be optimized before increasing output. For example; before increasing output, optimize gain to improve image quality. ▐ Additional Considerations Ensure that scanning time is kept to a minimum, and ensure that only medically required scanning is performed. Never compromise quality by rushing through an exam. A poor exam will require a follow-

[Page 41] Chapter 1 Safety 1 - 27 up, which ultimately increases the time. Diagnostic ultrasound is an important tool in medicine, and, like any tool, should be used efficiently and effectively. ▐ Output Display Features The system output display comprises two basic indices: a mechanical index and a thermal index. The thermal index consists of the following indices: soft tissue (TIs), bone (TIb) and cranial bone (TIc). One of these three thermal indices will be displayed at all times. Which one depends upon the system’s default setting or user choice, depending upon the application at hand. The mechanical index is continuously displayed over the range of 0.0 to 1.9, in increments of 0.1. The thermal index consists of the three indices, and only one of these is displayed at any one time. Each probe application has a default selection that is appropriate for that combination. The TIb or TIs is continuously displayed over the range of 0.0 to the maximum output, based on the probe and application, in increments of 0.1. The application-specific nature of the default setting is also an important factor of index behavior. The default setting is a system control state, which is preset by the manufacturer or the operator. The system has default index settings for the probe application. The default settings are invoked automatically by the Ultrasound System when power is turned on, new patient data is entered into the system database, or a change in application takes place. The decision as to which of the three thermal indices to display should be based on the following criteria: Appropriate index for the application: TIs is used for imaging soft tissue; and TIb for a focus at or near bone.Some factors might create artificially high or low thermal index readings, e.g. the presence of fluid or bone, or the flow of blood. A highly attenuating tissue path, for example, will cause the potential for local zone heating to be less than the thermal index displays. Scanned modes versus unscanned modes of operation affect the thermal index. For scanned modes, heating tends to be near the surface; for unscanned modes, the potential for heating tends to be deeper in the focal zone. Always limit ultrasound exposure time but do not rush the exam. Ensure that the indices are kept to a minimum and that exposure time is limited without compromising diagnostic sensitivity.  Mechanical Index (MI) Display Mechanical bioeffects are threshold phenomena that occur when a certain level of output is exceeded. The threshold level varies, however, with the type of tissue. The potential for mechanical biological effects varies with peak pressure and ultrasound frequency. The MI

[Page 42] 1 - 28 HS70A Service Manual accounts for these two factors. The higher the MI value, the greater the likelihood of mechanical bioeffects occurring. However, there is no specific MI value that means that a mechanical bioeffect will actually occur. The MI should be used as a guide for implementing the ALARA principle.  Thermal Index (TI) Display The TI informs the user about the potential for temperature increase occurring at the body surface, within body tissue, or at the point of focus of the ultrasound beam on bone. The TI is an estimate of the temperature increase in specific body tissues. The actual amount of any temperature rise is influenced by factors such as tissue type, vascularity, mode of operation, etc. The TI should be used as a guide for implementing the ALARA principle. The bone thermal index (TIb) informs the user about potential heating at or near the focus, after the ultrasound beam has passed through soft tissue or fluid, for example, at or near second or third trimester fetal bone. The cranial bone thermal index (TIc) informs the user about the potential heating of bone at or near the surface of, for example, cranial bone. The soft tissue thermal index (TIs) informs the user about the potential for heating within soft homogeneous tissue. TIc is displayed when you select a trans-cranial application. You can select TI Display in Utility > Setup > Display > Display.  Precision and Accuracy of Mechanical and Thermal Indices Displays The mechanical and thermal indices on the system are precise to 0.1 units. The MI and TI display accuracy estimates for the system are given in the Acoustic Output Tables manual. These accuracy estimates are based on the various range of probes and systems, inherent acoustic output modeling errors, and measurement variation, as described below. The displayed values should be interpreted as relative information to help the system operator achieve the ALARA principle through prudent use of the system. The values should not be interpreted as actual physical values from investigated tissue or organs. The initial data that is used to support the output display is derived from laboratory measurements based on the AIUM measurement standard. The measurements are then put into algorithms for calculating the displayed output values. Many of the assumptions used in the process of measurement and calculation are conservative in nature. Over-estimation of actual in situ exposure, for the vast majority of tissue paths, is built into

[Page 43] Chapter 1 Safety 1 - 29 the measurement and calculation process. For example, the measured water tank values are derated using a conservative, industry standard, attenuation coefficient of 0.3dB/cm-MHz. Conservative values for tissue characteristics were selected for use in the TI models. Conservative values for tissue or bone absorption rates, blood perfusion rates, blood heat capacity, and tissue thermal conductivity were selected. A steady state temperature rise is assumed in the industry standard TI models, and the assumption is made that the ultrasound probe is held steady in one position long enough for a steady state to be reached. A number of factors are considered when estimating the accuracy of display values: hardware variations, algorithm accuracy estimation and measurement variation. Variation among probes and systems is a significant factor. Probe variability results from piezoelectric crystal efficiencies, process-related impedance differences, and sensitive lens focusing parameter variations. Differences in the system pulse voltage control and efficiencies are also a contributor to variability. There are inherent uncertainties in the algorithms used for estimating acoustic output values over the range of possible system operating conditions and pulse voltages. Inaccuracies in laboratory measurements are related to differences in hydrophone calibration and performance, positioning, alignment and digitization tolerances, as well as variation among test operators. The conservative assumptions of the output estimation algorithms of linear propagation, at all depths, through a 0.3dB/cm-MHz attenuated medium are not taken into account in calculation of the accuracy estimate displayed. Neither linear propagation, nor uniform attenuation at the 0.3dB/cm-MHz rate, occur in water tank measurements or in most tissue paths in the body. In the body, different tissues and organs have dissimilar attenuation characteristics. In water, there is almost no attenuation. In the body, and particularly in water tank measurements, non-linear propagation and saturation losses occur as pulse voltages increase. The display accuracy estimates take into account the varying ranges of probes and systems, inherent acoustic output modeling errors, and measurement variations. Display accuracy estimates are not based on errors in, or caused by measuring according to, the AIUM measurement standards. They are also independent of the effects of non-linear loss on the measured values. ▐ Control Effect - Control Affecting the indices As various system controls are adjusted, the TI and MI values may change. This will be most apparent as the POWER control is adjusted; however, other system controls will affect the on-screen output

[Page 44] 1 - 30 HS70A Service Manual values.  Power Power controls the system acoustic output. Two real-time output values are on the screen: a TI and an MI. They change as the system responds to POWER adjustments. In combined modes, such as simultaneous Color, 2D-mode and pulsed Doppler, the individual modes each add to the total TI. One mode will be the dominant contributor to this total. The displayed MI will be from the mode with the largest peak pressure. ▐ 2D-mode Controls  2D-Mode Size Narrowing the sector angle may increase the frame rate. This action will increase the TI. Pulse voltage may be automatically adjusted down via software controls to keep the TI below the system maximums. A decrease in pulse voltage will decrease the MI.  Zoom Increasing the zoom magnification may increase the frame rate. This action will increase the TI. The number of focal zones may also increase automatically to improve resolution. This action may change the MI, since the peak intensity can occur at a different depth.  Persistence A lower persistence will decrease the TI. Pulse voltage may be automatically increased. An increase in pulse voltage will increase the MI.  Focal no. More focal zones may change both the TI and MI by changing the frame rate or focal depth automatically. Lower frame rates decrease the TI. The MI displayed will correspond to the zone with the largest peak intensity.  Focus Changing the focal depth will change the MI. Generally, higher MI values will occur when the focal depth is near the natural focus of the transducer.

[Page 45] Chapter 1 Safety 1 - 31 ▐ Color and Power Controls  Color Sensitivity Increasing the color sensitivity may increase the TI. More time is spent scanning for color images. Color pulses are the dominant pulse type in this mode.  Color Sector Width Narrower color sector width will increase color frame rate and the TI will increase. The system may automatically decrease pulse voltage to stay below the system maximum. A decrease in pulse voltage will decrease the MI. If pulsed Doppler is also enabled, then pulsed Doppler will remain as the primary mode and the TI change will be small.  Color Sector Depth Deeper color sector depth may automatically decrease color frame rate or change color focal zone or color pulse length. The TI will change due to the combination of these effects. Generally, the TI will decrease with increased color sector depth. MI will correspond to the peak intensity of the dominant pulse type, which is a color pulse. However, if pulsed Doppler is also enabled then pulsed Doppler will remain the dominant mode and the TI change will be small.  Scale Using the SCALE control to increase the color velocity range may increase the TI. The system will automatically adjust pulse voltage to stay below the system maximums. A decrease in pulse voltage will also decrease MI.  Sec Width A narrower 2D-mode sector width in Color imaging will increase color frame rate. The TI will increase and the MI will not change. If pulsed Doppler is also enabled, then pulsed Doppler will remain as the primary mode and the TI change will be small. ▐ M Mode and Doppler Controls  Speed M-Mode and Doppler sweep speed adjustments will not affect the MI. When M-Mode sweep speed changes, TI changes.

[Page 46] 1 - 32 HS70A Service Manual  Simultaneous and Update Methods Use of combination modes affects both the TI and MI through the combination of pulse types. During simultaneous mode, the TI is additive. During auto-update and duplex, the TI will display the dominant pulse type. The displayed MI will be from the mode with the largest peak pressure.  Sample Volume Depth When Doppler sample volume depth is increased, the Doppler PRF may automatically decrease. A decrease in PRF will decrease the TI. The system may also automatically decrease the pulse voltage to remain below the system maximum. A decrease in pulse voltage will decrease the MI. ▐ Doppler, CW, M-Mode, and Color Imaging Controls When a new imaging mode is selected, both the TI and the MI will change to default settings. Each mode has a corresponding pulse repetition frequency and maximum intensity point. In combined or simultaneous modes, the TI is the sum of the contribution from the modes enabled and the MI is for the focal zone and mode with the largest derated intensity. If a mode is turned off and then reselected, the system will return to the previously selected settings.  Probes Each probe model available has unique specifications for contact area, beam shape, and center frequency. Defaults are initialized when you select a probe. Factory defaults vary with probe, application, and selected mode. Defaults have been chosen below the FDA limits for intended use.  Depth An increase in 2D-mode depth will automatically decrease the 2D-mode frame rate. This would decrease the TI. The system may also automatically choose a deeper 2D-mode focal depth. A change of focal depth may change the MI. The MI displayed is that of the zone with the largest peak intensity.  Application Acoustic output defaults are set when you select an application. Factory defaults vary with probe, application, and mode. Defaults have been chosen below the FDA limits for intended

In October 1987, the American Institute of Ultrasound in Medicine (AIUM) ratified a report prepared by its Bioeffects Committee (Bioeffect Considerations for the Safety of Diagnostic Ultrasound, J Ultrasound Med., Sept. 1988: Vol.7, No.9 Supplement), sometimes referred to as the Stowe Report, which reviewed available data on possible effects of ultrasound exposure. Another report, “Bioeffects and Safety of Diagnostic Ultrasound,” dated 28th January, 1993, provides more up to date information. The acoustic output for this system has been measured and calculated in accordance with the December 1985 “510 (K) Guide for Measuring and Reporting Acoustic Output of Diagnostic Ultrasound Medical Devices,” except that the hydrophone meets the requirements of “Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment” (NEMA UD 2-1992).

[Page 48] 1 - 34 HS70A Service Manual ▐ In Situ, De-rated, and Water Value Intensities All intensity parameters are measured in water. Since water does not absorb acoustic energy, these water measurements represent a worst case value. Biological tissue does absorb acoustic energy. The true value of the intensity at any point depends on the amount and type of tissue and the frequency of the ultrasound that passes through the tissue. The intensity value in the tissue, In Situ has been estimated using the following formula: − ( 0 . 23 alf ) In Situ = Water e where: In Situ = In Situ Intensity Value Water = Water Value Intensity e = 2.7183 a = Attenuation Factor Tissue a(dB/cm-MHz) Brain .53 Heart .66 Kidney .79 Liver .43 Muscle .55 l = skin line to measurement depth (cm) f = Center frequency of the transducer/system/mode combination (MHz) Since the ultrasonic path during an examination is likely to pass through varying lengths and types of tissue, it is difficult to estimate the true In Situ intensity. An attenuation factor of 0.3 is used for general reporting purposes. Therefore, the In Situ value which is commonly reported uses the formula: − ( 0 . 069 lf ) In Situ ( derated ) = Water e Since this value is not the true in situ intensity, the term “de-rated” is used. The maximum derated and the maximum water values do not always occur at the same operating condition. Therefore, the reported maximum water and derated values may not be related to the In Situ (derated) formula. For example, a multi-zone array transducer that has maximum water value intensities in its deepest zone: The same transducer may have its largest derated intensity in one of its shallowest focal zones.

TIP Principles of Operation of the Diagnostic Ultrasound System Medical ultrasound images are created when the computer’s digital memory converts the high-frequency wave signals that are transmitted and received by the probe. As ultrasound waves propagate through the human body, they generate reflected signals whenever they encounter a change in density. For example, reflected signals are generated when signals pass from fatty tissues to muscle tissues. Reflected signals return to the probe where they are converted into electronic signals. The reflected signals are amplified and processed by analog and digital circuits that have filters for various frequencies and response time options. Then they are again converted into high-frequency electronic signals, and saved as a series of digital image signals. The monitor displays the image signals stored on the storage device in real time. The entire process of transmitting, receiving, and processing signals is controlled by the computer.

[Page 141] Chapter 5. Product Structure 5 - 7 Basic Structure of HS70A Overview HS70A consists of the Ultrasound System Part and the User Interface Part. However, when considered as an electronic structure, it consists of a Front End Part, a Back End Part, a User Interface Part, and a Power Part. A description of HS70A as an electronic structure is as follows: Front End Part refers to the PSA (Probe Select Assembly), BF (Beamformer), and CW (Continuous Wave Board). The main functions of the Front End Part are to deliver High Voltage Pulser to the probe, thereby generating ultrasonic waves, and to amplify the returning echo signal to process Digital Beamforming. The RF signal generated here is sent to the Back End Part. Back End Part refers to the BE (Back End) of the Ultrasound System Part as well as the PC Module. It generates various diagnostic images such as BW, Color Doppler, PW Doppler, Power Doppler, etc. from the RF signal generated by the BF (Beamformer), and displays the images on the monitor so that the user can view them. In addition, it incorporates new technologies such as SCI and SDMR to facilitate a wide variety of diagnostic exams. User Interface Part means the LCD monitor and control panel (including touch panel). The Power Part can be divided as AC-DC Power Module and DC-DC Power Module; AC-DC Power Module converts AC voltage into DC to supply power to DC-DC Power Module as well as PC power of the PC part. DC-DC Power Module supplies voltage to boards of the Ultrasound System, while the PC Power supplies voltage to the PC Part. Ultrasound System Part The main function of the Main Board is to implement the ultrasound data up to the stage before Scan Converter. It performs some Front End Part and Back End Part functions. This detects probes and sends system information and application information in accordance with

[Page 142] 5 - 8 HS70A Service Manual user environment to each Board. it performs TX Focusing and RX Focusing based on such information. When high voltage Pulser is sent to the probe according to TX Focusing, ultrasonic waves are generated; echo signals returning from the body go through an amplification circuit to undergo Digital Beamforming processing. The RF signal obtained here goes through various filtering and processing to generate image signals such as BW, Color Doppler, PW Doppler, CW Doppler, Power Doppler, etc., which are sent to the PC Module to be implemented on the monitor. The DC to DC Power Module supplies power to the Ultrasound System Part. The Ultrasound System Part consists of the following: • PSA(Probe Select Assembly) Board • AC(Analog Control) • BF(Beamformer) Board • BE(Back End Board) • DDM (DC to DC Power Module) • CW(Continuous Wave Board) PC Part It main function consists of the Scan Converter and image output circuits for displaying the ultrasound information generated by the Ultrasound System Part on the monitor. It also performs control panel and interface functions. The ultrasound image information from the Ultrasound System Part is connected to PC Part at PCIF with DMA method, and the ultrasound image is displayed through software DSC and VGA. Previous type of the ultrasound image scanner uses the Hardware DSC method, but HS70A uses the Software DSC and the ultrasound images are displayed on a LCD monitor. PC Power Supply uses Micro ATX as standard, and it supplies power to PC Part. The PC Part consists of the following: • PCIE(Peripheral Component Interconnect Express)

[Page 143] Chapter 5. Product Structure 5 - 9 • DVI(Digital Video Interface) • VGA(Video Graphics Array) • PC Mother Board • Rear Panel • PC Power Supply User Interface Part This part allows the user to view ultrasound images on the LCD monitor to make a diagnosis, and to control HS70A by using the control panel and touch panel. Images are sent by the Ultrasound Part to the LCD monitor and peripherals. Output images available include VHS, S-VHS, Composite and DVI, while input images include VHS and S- VHS. In addition, the control panel consists of various interfaces to allow the user to operate the system conveniently. The User Interface Part consists of the following: • LCD Monitor(LCD Inverter Board, LCD Control Volume) • AD Board • Control Panel Board • Touch Panel • Track Ball • Alpha-Numeric Key Board AC to Power Module It converts external 110/230V AC voltage to the DC voltage to supply power to DDM (DC to DC Power Module) of Ultrasound System Part, and it also supplies stabilized AC voltage to PC Power Supply of PC Part. Power circuit breaker prevents any possible troubles due to overcurrent.

[Page 144] 5 - 10 HS70A Service Manual Ultrasound System Part PSA PSA serves as an interface for the System and the Probe. Probe Connector has 4 of 408-pin Connectors and 1 of LEMO Connector and has the CW selection relay to support CW. Also, it has 3D Probe Drive Path, Probe Insert Path, Port Select Path and CW Path and it has the Relay circuit to select one probe out of 4 probes. [Figure 5.3 PSA Block Diagram] • Local Power distribution • LV/HV Power Switching • 4 Probe Port Support • Probe Check • 3D probe path

[Page 145] Chapter 5. Product Structure 5 - 11  High Voltage Switching Process HS70A 는 supports 128 Channels, and uses up to 192-Element Probes. Since the Beamformer’s Pulser and Receiver circuit structure has only 128 Channels, additional Element Selection is required. Element Selection uses 24 High Voltage Switches, and performs switching with the control signal sent from the Main Board’s Control Logic (CPLD). Control Signal is connected via Mother Board Connectorfmf. The inner structure of the High Voltage Switch consists of Shift Register and High Voltage FET.  High Voltage Switching Process It consists of circuits to choose one of four probes. It can use the relay of the latched type to select a probe chosen by user. The relay is operated by the probe select signal transmitted from the control logic (CPLD) of CW (Continuous Wave Board). Probe Select signal is connected through the Mother Board Connector. Probe Select signals are connected via the Mother Board Connector.  CW Probe Switching Steered CW Switching: Steered CW has, separate from the Beam former Board, Tx 29CH and Rx 29CH and, by using Not latch Relay, it converts the signal line from Phased Array Probe to the CW Board at Steered CW Mode. Because it has 29CH, there are 15 AGN20012s for CW Tx and there are 15 AGN20012 for CW Rx. Static CW Switching:Static CW has Tx 1CH and Rx 1CH separately from the Beam Former Board. Signal lines from Pencil Probe in the Stactic CW Mode will be directly connected to the CW Board without Relay.

[Page 147] Chapter 5. Product Structure 5 - 13 • The main function of the Analog Control board is to control the motor of 3D Probe, to supply clocks to the entire system and to monitor the status of power. • Motor Part controls the stepping motor inside the 3D Probe. • HV Filter is a high voltage filter used in BF. • Clock Part generates system Clock 61.6Mhz used in BF and BE. • Pulser Sensing Part monitors the status of High Voltage and current used in the BF board. • ATGC Part supports analog time gain control curve used in BF. • AC Power generates power for the AC & PSA board. • Probe Part checks Probe port selection, • Probe ID read, and Probe Insert of the PSA board at all times. • 3D Probe Motor Driver • System Clock Drive • Pulser Voltage Sensing • HV Mux Sensing • ATGC • AC Power • Probe Check (ID/Insert/Port) The operational principle of the 3D Probe is the implementation of 3D mode through the actuation of Stepping Motor. The Motor Board performs feedback control with SIN and COS waveforms that have a 90 -phase difference with the 3D Probe. Here, the 3D Probe provides a Null Position signal to the Motor Board, and the Motor Board provides One Frame signal, which is the standard signal for obtaining 3D images, to BE Board. It monitors the voltage of HV Power in the BF Board and sends it to PC. It provides the ATGC Curve to the BF Board.

[Page 148] 5 - 14 HS70A Service Manual Beam Former Board Beamformer board is located between PSA and Back-end and it sends a ultrasound signal focused on a specific position of the body and amplifies the received signal to convert it to a Digital signal. Then it beamforms the signal and relays the Focused data to Back-end for Mid- processing. BF Board consists of Pulser, TR Switch, LNA, TGC, ADC and BFIC. [Figure 5.5 Front End Block Diagram] • Pulser: consists of 192 channels and it can run 192 element Probes. • TR Switch: deletes the HV element from Probe to prevent it from flowing to LNA. • LNA: amplifies the received ultrasound signal and TGC Amp compensates the attenuation due to Depth to send the signal to ADC. • ADC: converts the amplified Echo signal to digital data. • BFIC: It Rx focuses the RX echo signals of 128 CH and sends them to BE Part. • TX FPGA: The generated exciting pulse signal is entered into Pulser, converted to high-

The TX Pulser uses the high voltage and Exciting pulse data provided by the DC-DC Module to generate Bipolar Pulser. Bipolar Pulser uses PSA (Probe Select Assembly) to send to the Probe Element, thereby generating ultrasonic waves.  Receive Channel The Receive Channel serves the function of an Analog Digital Conversion, which enables Beamforming by amplifying the Echo propagated through, and reflected from, the media of human body. It consists of a Limiter, a Pre-Amp, a TGC-Amp, a Low-Pass Filter, and an A/D Converter. 1) Limiter It removes unnecessary signals from the Echo signals returned through High Voltage Switch of PSA(Probe Select Assembly. Tx Pulse up to 180 Vpp and echo signals of a few mV are mixed together, but since the RX data actually needed are echo signals of extremely small magnitude in mV range, the Tx Pulse must be eliminated before they are sent to the Pre-Amp. The Limiter removes signal over approximately 0.6V before sending

[Page 151] Chapter 5. Product Structure 5 - 17 the echo signal to the Pre-Amp. 2) Pre-Amp The Pre-Amp amplifies the unprocessed small-magnitude echo signal in mV range. 3) TGC-Amp The TGC (Time Gain Compensation) Amp consists of 4 channels per one unit. It compensates for the time or distance-dependent reduction characteristics of echo signals that have been propagated through, or reflected from media. 4) Anti-aliasing Filter (Low Pass Filter) The Low-Pass Filter filters the nose out of Stop Band, which is not the band of ultrasound signals. It also serves as an anti-aliasing filter, minimizing the aliasing phenomena that may occur with high frequency probes such as the 7.5MHz probe. Aliasing phenomena of high-frequency probes are caused by the restriction of the sampling clock in BF ASIC. 5) A/D Converter This converts an analog signal into a digital signal to be used for Digital Beamforming.  Digital Beam forming Ultrasonic waves generated by a probe use a Channel method that utilizes multiple Elements to perform TX Focusing. Ultrasonic waves generated from each channel are reflected by media and return as reflected echo signals. However, the echoes do not return to the Probe Element simultaneously; they return to each Element at different times, which necessitates a way to compensate for this time difference. It is required to perform RX Focusing; it is also very important for generating ultrasound images. Digital Beam forming takes the echo signals entering the Probe Element and samples the data at the junction of the time axis and the curve, which is then stored in the memory. When sampling is complete, the data accumulated in the memory have been time-compensated when they were stored; time compensation is performed by the Sampling Clock itself. RX Focusing is completed by simply reading the data stored in the memory and adding them. Since this method requires different Sampling Clocks for each Element, the VSCG (Variable Sampling Clock Generator) is necessary. The VSCG (Variable Sampling Clock Generator) uses 61.6Mhz, which is same as the A/D Sampling Clock; necessary data is generated within BF ASIC (MCB124A).

It uses PSA (Probe Select Assembly) to send to the Probe Element, thereby generating ultrasonic waves.  Receive Channel The Receive Channel serves the function of an Analog Digital Conversion, which enables Delay & Focusing by amplifying the Echo propagated through, and reflected from, the media of

[Page 154] 5 - 20 HS70A Service Manual human body. 1) LNA: It amplifies the received signal. 2) Delay & Focusing: It combines Rx input signals from 29 channels as a single signal. 3) Mixer: To detect Doppler signals, it mixes RF signal and signal which has the same transmission frequency. 4) I/Q Signal: To find a direction of blood flow, enter a signal which has 90 ° phase difference from the standard signal. 5) Audio Circuit: After mixing, remove the higher frequency element for the signal to get the Doppler frequency signal. 6) ADC: It converts a digital signal to an analog signal.

[Page 155] Chapter 5. Product Structure 5 - 21 Back End Board Back End Board (hereinafter BE Board) can be divided into DSP (Digital Signal Processing) Part, DMA & RTC Part, and, Analog Sound Part. The DSP Part receives RF data and CW I/Q data from the BF Board and CW Board and processes the data into image data such as BW Image, PW Doppler, CW Doppler, Color Doppler, Power Doppler, etc. The created Image Data is processed by DMA & RTC Part of BE Board for Frame Average etc., and then sent to the PC Part through PCI BUS to be calculated by Software DSC. The Analog Sound Part receives Doppler sound data from the DSP Part, processes the data with the Digital Analog Converter, amplifies and sends them to the speaker. BE Board consists of ASIC (MCB028A), FPGA, Analog Sound part and more. [Figure 5.8 Back End Board]

[Page 157] Chapter 5. Product Structure 5 - 23 ▐ Operational Principles of DSP Part  Image Data Processing in BW Mode and M Mode RF Data generated by the BF Board is entered as FPGA Input. The entered RF Data is converted into computable RF Data at FPGA Input, and then entered as the input for ASIC (MCB028A). ASIC(MCB028A) generates BW mode Image Data (hereinafter, BW Data) and sends it to FPGA. ASIC(MCB028A) creates BW Data and processes FSI (Full Spectrum Image), Spatial Compound Imaging (SCI), Trapezoidal imaging, Synthetic aperture, and more. To generate BW Data, it receives RF Data input and go through the process of DTGC (Digital Time Gain Compensation), Decimation, Quadrature mixer, Envelope detection, Log compression and several filtering. BW Data generated by ASIC (MCB028A) as described above is entered into FPGA again. It goes through FSI (Full Spectrum Image) and Lateral filter to remove Multibeam artifact and BW Data is sent to FPGA. Note that the BW Data can be used as Motion mode Image Data.  Doppler Image Data Processing RF Data generated by the BF Board is entered as FPGA Input. The entered RF Data is converted into computable RF Data at FPGA, and then entered as the input for ASIC (MCB028A). ASIC (MCB028A) receives RF Data input and processes through DTGC (Digital Time Gain Compensation), Decimation, Quadrature Mixer, etc. to create I/Q data (In-phase & Quadrature Data). I/Q Data is entered into FPGA again. I/Q Data is processed at FPGA to generate Doppler Data and it is sent to DMA & RTC Part. Detailed descriptions are as follows. FPGA which received I/Q Data filters the data and filters CW I/Q Data from CW Board in the same way to send the final Doppler Data to PC Part. PW and CW cannot be processed simultaneously, therefore all operations are controlled by the internal control process. In addition, I/Q Data go through a Clutter Filter and are sent to a FFT (Fast Fourier Transform) circuit for generating Doppler Spectrum, which isolates the basic elements of Doppler, i.e. power, velocity, and variance, to generate Doppler Data. It is entered into DSP FPGA again and is sent to DMA & RTC Part of BE Board. Doppler Sound Filtered I/Q Data from FPGA go through the Clutter filtering to remove the Wall Noise from Doppler DSP and is processed with Hilbert transform. The direction of sound is removed to generate Doppler Sound.

[Page 158] 5 - 24 HS70A Service Manual  Color Image Data Processing RF Data generated by the BF Board is entered as FPGA Input. The entered RF Data is converted into computable RF Data at the ASIC (MCB028A), and then entered as the input for ASIC (MCB028A). ASIC (MCB028A) receives RF Data input and processes through DTGC (Digital Time Gain Compensation), Decimation, Quadrature mixer, etc. to create I/Q data (In-phase & Quadrature Data). I/Q Data is entered into FPGA again. I/Q data is processed at ASIC (MCB028A) to generate Color data and is sent to PC Part. Detailed descriptions are as follows. FPGA that receives I/Q data will send it to ASIC (MCB028A) to detect Color elements. However, as Color elements include Wall (blood vessel wall) Noise, it is sent to FPGA again for Rejection, Smooth Filter and Post filter processing. In these processes, Color Data is completed and sent to DMA & RTC Part of the BE Board. ▐ Operational Principles of Analog Sound Part The Analog Sound Part processes Doppler Sound and sends it to the speaker. Doppler Sound is generated in the Doppler Part, and sent to the Analog Sound Part. Doppler Sound goes through the Audio Digital Analog Converter process, because the speaker only receives analog sound waves. Next, noise removal and Doppler Sound amplification are performed before sending to the speaker. ▐ Operational principle of DMA & RTC Part (including FPGA function)  DMA Part DMA (Direct Memory Access) consists of FA (Frame Average), DMA and ECG In/Out Part. FA (Frame Average) processes BW, Doppler, and Color Data by averaging the current frame’s scan line data and the previous frame’s scan line data. DMA temporarily stores the BW, Doppler, and Color Data that have been Frame Averaged, to send them through PCI BUS when requested by the PC Part. It also stores ECG Data and sends it in the same manner. Since DMA uses the PC Part and the DMA Path for processing, it plays a very important role in enhancing the performance of the product.

[Page 159] Chapter 5. Product Structure 5 - 25  RTC Part RTC (Real Time Controller) creates the standard signal for the entire system operations in real time to control the system operations. It generates PRF(Pulse Repeat Frequency), OF(One Frame), RP(Rate Pulse), Linotype and Scan Line, which are required for BF Board and DSP Part of the BE Board. Also, internally it controls data flow at the DMA FPGA.

[Page 203] 5 - 2 HS70A Service Manual Probes The probe is a device that sends and receives ultrasound for acquiring image data. It is also called a Transducer or Scanhead. The system limits patient contact temperature to 43°C, and acoustic output values to their respective U.S. FDA limits. A power protection fuse circuit protects against overcurrent conditions. If the power monitor protection circuit senses an overcurrent condition, then the drive current to the probe is shut off immediately, preventing overheating of the probe surfaces and limiting acoustic output. ▌ Probe List The ultrasound image scanner uses probes to obtain graphic data of the human body and then displays it on the screen. Always use application-specific probes in order to obtain the best quality images. It is also important to use a preset that is best suited to the particular organ being scanned. ■ Probe Application and Presets The types of probes, applications, and presets available with this product are as follows: Small Parts Bowel, Breast, Breast1, Testicle, Thyroid Vascular Arterial, Carotid, Venous L3-12A MSK Shoulder/Knee, Hand/Foot, Elbow/Wrist, Penetration, Pediatric Hip st Abdomen General, Superficial, Pediatric ABD Small Parts Bowel, Breast, Testicle, Thyroid LA3-16A Vascular Arterial, Carotid, Venous MSK Shoulder/Knee, Hand/Foot, Elbow/Wrist, Penetration MSK General, Superficial LA3-16AI Intraoperative General Small Parts Bowel, Breast, Testicle, Thyroid Vascular Arterial, Carotid, Venous Abdomen General MSK General Small Parts Breast, Testicle, Thyroid LA4-18B Vascular Carotid, Superficial MSK General, Superficial Abdomen Aorta, General, General1, Pediatric ABD, Penetration, Renal, Urology CA1-7A OB 1 Trimester, 2 Trimester, 3 Trimester, Fetal Heart, NT

[Page 214] Chapter 5. Probes 5 - 13 Ultrasound Transmission Gel For successful acoustic signal transmission, please only use the ultrasound gels approved by Samsung Medison. ■ The use of inappropriate ultrasound gels could result in damages in the probe. Using damaged probe could cause injuries such as electric shock in users or patients. WARNING ■ Do not use ultrasound gels or contact media that contain the following contents. – Oils such as mineral oil, cooking oil, gasoline, solvents, rust inhibitors, lanolin, paraffin-based grease, ester and excessive silicon-based release agent. – Alcohols such as acetone, methanol, plasticizer (dioctylphtalate) or denatured alcohols. – Glacial acetic acid and iodine. – All types of lotions or gels that contain aromatic substances. ▌ Gel Warmer (Optional) The Gel Warmer keeps the ultrasound gel warm. Warming up ultrasound gel takes approximately 5 minutes. ■ Always turn the Gel Warmer off when it is not in use. ■ Do not put your hands inside the Gel Warmer, as it may burn your skin. ■ Do not use the Gel Warmer for purposes other than to control the temperature of ultrasound gel. ■ Do not place the probe or any other equipment inside the Gel Warmer. ■ Do not touch the power terminal of the Gel Warmer while you are examining a patient. There is a risk of electric shock from leakage current. ■ Do not apply excessive force to the Gel Warmer, or you may damage its support parts.

[Page 215] 5 - 14 HS70A Service Manual Using Sheath Sheaths are recommended for clinical applications of an invasive nature, including intraoperative, transrectal, transvaginal, and biopsy procedures. Samsung Medison does not supply sheaths, so you should purchase appropriate supplies from your regular supplier. ■ Always keep sheaths in a sterile state. ■ Sheaths are disposable. Do not reuse them. ■ If sheaths are torn or soiled after use, clean and disinfect the probe. ■ In neurosurgical applications, a disinfected probe must be used with sterile gel and a sterile pyrogen-free sheath. ■ If the sterile sheath becomes compromised during neurosurgical applications involving a patient with Creutzfeldt-Jakob disease, the probe cannot be successfully sterilized by any disinfection method. ■ Some sheaths contain natural rubber latex and talc, which can cause allergic reactions in some individuals. Please refer to the FDA Medical Alert released on March 29, 1991. ▌ Installing the Sheath 1. Put on sterile gloves. Unpack the sheath and fill it with acoustic coupling gel. 2. Insert the probe into the sheath and pull the latex tip to cover the probe completely. If possible, cover the probe cable as well. 3. Ensure that there are no air bubbles within the ultrasound gel. If necessary, secure the sheath to the probe and the probe cable. 4. Dispose of the sheath after use.

[Page 216] Chapter 5. Probes 5 - 15 Probe Precautions ■ Do not apply mechanical shocks to the probe. ■ Do not place the probe cable on the floor where the cable can be run over by equipment wheels, etc. Do not apply excessive force to bend or pull the CAUTION cable. ■ Do not immerse the probe into any inappropriate substances such as alcohol, bleach, ammonium chloride, and hydrogen peroxide. ■ Do not expose the probe to temperatures of 50 ° C or higher. The probe can easily be damaged by improper use or by coming into contact with certain chemical substances. Always follow the instructions in the user manual to inspect the probe cable, case and lens before and after each use. Check for cracks, broken parts, leaks and sharp edges. If there is any damage, immediately stop using the probe and contact Samsung Medison’s servicing department. Using damaged probes may result in electric shocks and other hazards to the patients and/or users. ▌ Use and Infection Control of the Probe No neurosurgical treatments or examinations should be carried out on a patient with Creutzfeldt-Jakob disease (critical brain disease caused by virus). If the probe has been used on such a patient, it cannot be sterilized by any method whatsoever. Sufficient washing and disinfecting must be carried out to prevent infection. This is the responsibility of the user who manages and maintains the disinfection procedures for the equipment. Always use legally approved detergents. The ultrasonographic image scanner uses ultrasound, and it makes direct contact with the patient when in use. Depending on the types of examinations, such contact can be made to a wide variety of locations, including the ordinary skin or the location of blood transfusion during surgery. The most effective method to prevent infection among patients is to use each probe only once. However, probes may need to be reused, as they are complex in design and expensive. Consequently, the safety instructions must be followed carefully in order to minimize the risk of infection among patients.

[Page 217] 5 - 16 HS70A Service Manual ▌ Electric Shocks The probe uses electrical energy. If it touches conductive materials, there are risks of electric shocks to the patient or the user. ■ Have the system regularly inspected by Samsung Medison technicians for electric leaks. ■ Do not immerse the probe into liquid. ■ Do not drop the probe or apply mechanical shocks. ■ Inspect the housing, strain relief, lens and seal for damage, and check for any functional problem before and after each use. ■ Do not apply excessive force to twist, pull or bend the probe cable. ■ The power protection fuse protects the probe and the product from excess current. If the power monitoring protection circuit detects excess current, it immediately shuts off the current to the probe in order to prevent the probe surface from overheating and to restrict the ultrasound power output. ■ The temperature of the product for making contact with patients is limited under 43°C. The ultrasound power output (AP&I) is in compliance with US FDA standards.

[Page 218] Chapter 5. Probes 5 - 17 Cleaning and Disinfecting the Probe Using an inappropriate cleaning or sterilizing agent may damage the product. ■ Always use protective eyewear and gloves when cleaning and disinfecting probes. ■ Inspect the housing, strain relief, lens and seal for damage, and check for WARNING any functional problem after cleaning and disinfecting the probe. ▌ Information of Detergent, Disinfectant, and Ultrasound Gel ■ Classification of Disinfectants To maintain the performance of ultrasound probes, proper maintenance is required. As ultrasound probes are classified into critical, semi-critical, or non-critical devices based on the standards of FDA guidance*, proper disinfection, cleaning or sterilization methods for that classification should be used. Classification Contact Area Application Probe Level Selection Criteria Non-critical Convex, Linear array, and Intact skin Low level disinfectant device sector transducers Semi-critical Mucous membrane and Endocavity High level disinfectant device damaged skin High level disinfectant or Critical device blood, sterile tissue, etc. Intraoperative, TEE sterilization *Guidance for Industry and FDA Staff - Information for Manufacturers Seeking Marketing Clearance of Diagnostic Ultrasound Systems and Transducers - Appendix D

[Page 240] Chapter 5. Probes 5 - 39 Biopsy A biopsy is an examination method that surgically extracts tissue from the patient for examination. The probe and the biopsy kit are used together when conducting a biopsy with the ultrasonographic image scanner. The ultrasound system shows the needle, which penetrates through the skin surface and veins, along with the examination location, minimizing the risk to the patient. Biopsy Kit Components The biopsy kit consists of the adapter, needle guide and needle. The components vary depending on the probe type. [Figure 5.5 Biopsy Kit Components] – Adapter: Secures the needle guide to the probe tightly. – Needle Guide: Guides the angle (direction) of the needle so that it can reach the examination location accurately. It also secures the needle so that the needle is not loose. – Needle: This is the needle that is inserted into the patient’s body. Biopsy kits supplied by Samsung Medison do not include needles. – Sheath: Prevents the probe and adapter from getting soiled by any unwanted substances during the examination (blood and other bodily fluids). – Ultrasound Gel: The space between the probe and the sheath is filled with the ultrasound gel to obtain images of the best quality.

[Page 241] 5 - 40 HS70A Service Manual Using the Biopsy Kit ■ Only use the needles approved by the country’s government. ■ Verify the condition of the biopsy needle before use. Do not use a bent biopsy needle. ■ The biopsy needle may bend during tissue penetration. The precise location of the needle must be checked by monitoring the echo generated from the needle. ■ Never use the biopsy kit to biopsy prostate tissue. ▌ Before Using Biopsy Kit ■ Do not attempt to use the biopsy until you read the instructions for installing the sheath and verifying alignment of the needle guide. ■ Always ensure that the probe and the needle guide are secured on both the WARNING left and the right. ■ Do not use in IVF, CVS, or PUBS procedures. Ultrasonographic scanning using the biopsy kit must be conducted by medical doctors or experienced medical staff with appropriate qualifications. Always, without fail, verify all safety procedures and disinfection. Other brands may not properly fit Samsung Medison probes. Use only Samsung Medison - approved biopsy kits. Improper installation may result in patient discomfort. Inspect all components. Ensure that the biopsy kit you are using is the correct one for the probe, the system, and system software.

[Page 242] Chapter 5. Probes 5 - 41 ▌ Biopsy Procedure The system generates a needle guideline through the displayed real-time ultrasound images to indicate the anticipated path of the needle. You can use this guideline to ensure that the needle or instrument is following the correct path. 1. Ready the patient according to the procedure appropriate for the examination objectives. 2. Install the sheath and the biopsy kit. 3. Set the system controls for the biopsy procedure. If necessary, apply acoustic gel to the patient. 4. Begin scanning the patient. Adjust the patient so that the location for examination fits into the needle guideline on the screen. 5. Install the needle into the needle guide for use. Perform the puncture by sliding the needle through the groove in the guide until the needle intercepts the target. To keep the needle securely in the needle guide, press down on the top of the biopsy adapter with your index finger. 6. When the examination location is reached, take the needle out of the needle guide. 7. Detach the needle guide, adapter and sheath from the probe. 8. Dispose of the components that are not designed for reuse. ▌ Needle Guide Alignment ■ The needle used for this alignment verification must not be used for the actual procedure. Always use a new, sterile needle for each biopsy procedure. WARNING ■ To assist in accurate projection of the needle, use a straight, new needle for each alignment procedure. Alignment of the needle guide displayed on the system is for the purpose of verifying whether the needle and the needle guide are properly installed. This must be done prior to the biopsy examination. Contact Samsung Medison ‘s servicing department for service. Reverberation or other tissue artifacts may produce false needle images, which can cause confusion. Ensure that the needle path is along the guideline, and that you are not using a false needle image to locate the needle. 1. Attach the biopsy kit. 2. Set the system depth for the procedure to be performed and select the Biopsy menu. 3. Immerse the probe into the water bath, and insert the needle into the needle guide. 4. Confirm that the needle image is on the needle guidelines. If so, the needle guide is properly aligned. 5. If the needle image is out of the needle guideline, check the needle guide or the probe adapter.
