It will also attempt to present how the service manual and FUN are coupled together and complement one another. Here you will find a general explanation of the concept structure, the various sections comprising the service manual and how they can be used most effectively for trouble-shooting and repair. The contents of the service manual will support service technicians during on-site trouble-shooting and faulty component isolation. While the instructions are not a substitute for an in-depth knowledge of the system, its components or the underlying physics, they will facilitate, on the one hand, trouble-shooting procedures for the less experienced experienced technician in performing essential measurements and tests. The measurements of power supplies, etc. The service manual should not and does not take the place of an error catalogue. In most cases hardware faults are easily and quickly located. Intermittent errors require more time and patience specially if they are generated by software or by the combination among two or more system components. It is not within the scope of the service manual to list all possible tests. Its purpose is to support the search for frequently occurring errors, to allow the technician to limit the error search to certain functional or employed is which personnel Introduction qualified Authorized personnel only must carry out any installation, assembly, maintenance, extensions, regulation, modifications, or repairs.

From <System Check> you can also verify the correct operation of “Gradients” and “RF Pulse”. Regarding the RF pulse, you must know the correct amplitude ratio between transmitted and reflected RF pulse (Pd/Pr>4) which shows that the connection is correct and that the transmitting coil (BTX) tuning is correct. Conversely, the absence of the RF pulse may be due to: A malfunction of the ACM receiving power (fuse, cable, etc.). Bad tuning of the transmitting coil. If the ratio is about 1 (i.e. all the power is reflected), the problem could be due to a bad connection between RF amplifier and transmitting coil or a broken component inside the transmitting coil. For example the central capacitor on the tuning circuit inside the “gantry”. A wrong value of the frequency set in the “Homogeneity” calibration. As for the receiving chain, you are advised to use the standard machine settings (central frequency search, noise level, S/N for the various receiving coil and sequence calibration, etc.). 141012700 VER.2

A small frequency shift is normal and is compensated by the system. A frequency shift usually is related to a thermal shift, usually, due to the environmental thermal shift. During the day the temperature of the room increase and the TCM has to follow this shift decreasing the power sent to the Magnet to warm up it. In case of big Magnet thermal shift, perform the Temp Monitor, to follow in real time, temperature and provided power to every channel.

[Page 56] Example of selective noise with a given frequency Fig. 19: by created (GE-FLASH, types interference sequence frequencies, different radio using external by patients on hardware modules – RF external frequencies – RF frequencies within the system due to the failure of any Image quality Common interference problem analysis The most frequent cases are the presence of artifacts on the image generated some Electronics modules inside the Electronics unit or “spikes”. A typical case of the radio-frequency problem generates a strip on the image; this can be more or less thick. In both cases, the noise is selective, but when the strip is thin, this means that the noise has only a single frequency. On the other hand, if the strip is thick, it is typically a frequency modulation. Instead, the “spikes” could be classified as a large bandwidth problem that is usually generated by poor power supply or by certain motors (e.g. from elevators, air conditioning, etc.). After performing all the system's calibrations and the relative quality tests, check that the system is operating smoothly by performing scans Spin-Echo, Turbo-Multi-Echo, etc.). For this type of testing, perform several acquisitions on all the four coils and assess the quality for each type of sequence. More specifically, the images obtained must be observed in order to exclude the presence of artifacts (such as lines, light spots, bands, etc.) and magnetic fluctuations in DC mode (e.g. blurring) and in AC mode (e.g. ghosts). In order to check that the signal/noise ratio is good and that the contrast is appropriate. Consider that some related problems (for instance lines, spots, etc.) may be caused by:

If the Patient’s anatomy is not correctly set in the center of the Magnet FOV area or if his body is touching and loading (no cushion) the receiving coil or the transmitting coil you’ll have very bright areas on the images as shown in the following examples. The scout lines are useful to identify the center of the FOV area where the interested anatomy must be set. some cause may line power in spikes strong that "Moire" artifact probably due to strong spikes on the power line All the current scans are to be taken in multi slice mode with the slices oriented as desired.

Another critical factor for the noise level is the presence of personal computers or other instruments that could create some interference by interference (lines on the images) or, more likely, white noise (noisy images). significantly. Both checked, because they sometimes generate problems. As a matter of fact, it has often been noted that, if the grounding problem is solved, the average-fft level decreases to a normal value (around 500). A short list including things to be avoided during installation is given below: Detecting artifacts on images Necessary tools in the camera perfectly step, not laser by <Shielding> step source other computers, problems, any of or different sources system between to possible service menu. If the problem has not been identified data all close off transmit Shielding efficiency This section covers some problems regarding high noise levels in the system room and their possible solutions. These kinds of problems could be generated by several things, such as: the power line cable lacking a good filtering system, network lines to installed shielded. In all these cases, the normal noise level increases until it exceeds the warning noise threshold, to the detriment of the quality and resolution of the images so obtained. This is to say that everything (line cables, personal computer, network cable, central phone line, etc.) in the room must be checked very carefully before installing the system to avoid any problems after installation. Therefore to reduce the noise level in the room, you must ascertain in advance which are the possible causes of the problems by acquiring images in different conditions. For example, this can be done by turning checking the average-fft value by clicking on the <Automatic> yet, proceed by making sure that all power lines use a line filter, that there are no other critical instruments in the system room and that every ground cable of the machine is properly connected. The purpose of this calibration is to check that no external noises are present in the signal picked up by he coil, such as radio-frequencies which would generate lines or light spots on the image. Moreover, the procedure checks that the noise level does not exceed a pre-set threshold value. The program is based on running a sequence that carries out a simple acquisition of the noise picked up by the receiving coil. By submitting it to Fourier's transform, you can detect the spikes resulting from external radio frequencies and to calculate the average noise level. With regard to these problems, we recommend putting the power line through an UPS system, so that the power line, that arrives at the 141012700 VER.2

It is thus <FFT> <Run> Put the homogeneous phantom inside the knee coil Under ARAS, select the then Set the possible to visualize the noise peak better Selective noise with a given frequency: a single peak will be displayed at that frequency; the higher the dB of the noise the higher the peak A large bandwidth noise (white noise): the whole level of the signal increases; this means that the noise in the room is too high To improve the signal display, click on the set a number around 20 Please note that a continuous signal corresponds to co-ordinate 1. This is the so-called offset that is always present. Therefore, this spike must not be considered for the purpose of evaluating the situation. In the event of persistent interference, on-site measurements must be taken exactly like those taken before installation. In addition, you must check that noise is not generated by the electronics. You must also make sure that any type of lines or spots does not affect the images. For this reason, some test scans must be taken. Conversely, if the noise level exceeds the threshold, it is likely that the receiving chain is malfunctioning or not properly calibrated. Please note that the cause of this might be white noise picked up directly by the coil. Therefore, you are advised to check that there are no possible sources near the machine and that the shielding is properly sealed. A method to understand how the noise level changes during the day is described, so it will be possible to look at noise variations in real time. Here are the operations useful for this check: ● ● ● ● ● ● When the previous operations are completed verify if the level of the signal is close to 1 K (first step) of the vertical grid, or if the “ variable in the information window has a value of around 1350, that means that the noise level is good (average-fft less then 500). If the level is higher, you can verify the noise level when a patient puts a limb inside the coil. <Run> <Automatic> <Shielding> Automatic Shielding Test Position the knee coil 2 with the geometrical phantom placed in axial position into the magnet Under ARAS select Look at the message sent by the calibration procedure.

Set the Frequency to 5 K to visualize a larger bandwidth (at least ± 20 kHz from the magnet frequency) and Y-axis to 1 K. If a central peak appears, usually is the ACM oscillator and means that the receiving channel is not properly calibrated. The meaning of this test is check if any radio frequency peaks appear close to the magnet central frequency (indicated by 0 kHz): if they appear they can generated noises on the images.

Check each module and cable, one at a time. If the problem is external you must check as described in the previous point. In fact when a patient's limb is inside the coil every external disturbance is increased, because the patient acts as an antenna. Therefore, at first you must check to see if the shielding parts are correctly applied to the patient and if each ground cable is fixed, then check what source could create the rise in noise. If you find something such as a personal computer, telephone or laser printer, that could be a source of noise, you will probably have to apply the solutions described previously, decreasing the noise level in the room (average-fft value around 500) until good quality images are obtained. In the same way you can study RF interference using the service menu. Also in this case you can have different kinds of disturbance: 1. 2. In the first case, set <Test> whereas, in a frequency modulation (case 2) is present on the images, always in <FFT> of peaks, will be displayed. 141012700 VER.2

These commands are processed (multiplexed and synchronized) by the ACM, then it processes the commands digitally and sends the driving RF signal to RFA (in connector RF). It sends the GATE signal to enable the RFA as well. The RFA amplifies the RF signal (impulse) and sends it through RFOUT connector to the RFAOUT of the filter panel connected to the MBTX connector of the magnet panel (BTX, flexible pressed matter circuit, fixed inside GANTRY).

Remember to insert a 10 <Run> under present 10 test temperature Strategy Thermal control The magnet must always be at the correct temperature, to achieve this result three dedicated modules have been fitted to the system. The first one is the TCM module, installed inside the Signal Box present into the Electronics unit, it has to manage the temperature values coming from the Magnet and drive the TCM (installed inside the Electronics Unit as well) that sends power to the heaters fitted into the Magnet structure. The last board is the NTC that is installed on the right side of the magnet; a small-dedicated panel used to check it is installed on the magnet's side cover. Resistors are fitted to the board and their values are calculated by taking note of the value of the thermal sensors in the magnet in order the make all the Magnet exactly equal one to the other. This means that every magnet has its own NTC board. It collects the data coming from the temperature sensors and receive the power for the heaters. To check if the magnet is at the correct temperature, perform the automatic <Troubleshoot.> <Temp. Check> coil before to perform this test. This test will give some information as shown in the following figure.
