Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Failure patterns typical of this equipment class - general BMET reference, not verified against this exact unit's own service history unless flagged. Severity is a category-level estimate.
Helium / cryogen pressure fault
HighSymptoms: Cold-head fault, quench alarm.
Root cause: Cold-head compressor wear or helium loss.
Gradient coil overheating
HighSymptoms: Sequence abort, thermal alarm.
Root cause: Cooling loop restriction or coil wear.
RF coil element failure
MediumSymptoms: Signal dropout, noise-band image artifact.
Root cause: Coil element or cable damage.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or RAID degradation.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A structured starting point derived from the failure modes above. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Helium / cryogen pressure fault
- Confirm the presentation - typically cold-head fault, quench alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: cold-head compressor wear or helium loss.
- Isolate the affected subsystem using the manufacturer's functional check or self-test, where one is provided.
- If the fault is confirmed and not a field adjustment, service or replace the rF receive coil per the manufacturer's service documentation.
- Return the device to service only after the manufacturer's functional and applicable electrical-safety checks pass.
- Record the findings, any parts used, and the verification results in the maintenance history.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
A gradient cable in the ACGD cabinet may be missing a spacer that prevents connecting the gradient cable terminals in the wrong polarity on X gradient amplifier. This could cause images to be flipped left-right with incorrect orientation annotation.
- RECALL
GE Healthcare has become aware of a potential safety issue involving MRI systems due to software versions not being maintained properly at some sites.
- RECALL
At certain sites, the MRU may not be connected to the magnet. In emergency situations, a disconnected MRU could delay removal of a ferrous object from the magnet, potentially resulting in life-threatening injuries. The MRU must be connected to the magnet at all times.
- RECALL
Potential safety issue due to a required torque check on three bolted joints of the Revolution CT scanner. No injuries or illnesses reported.
- RECALL
A required quality control test was not performed during installation associated with the software of the Revolution CT scanner.
- RECALL
The alignment lasers are missing the labels required by radiation safety regulations.
- RECALL
Possible misdiagnosis or inappropriate treatment based on the image. Signal homogeneity may be affected when BRAVO applications are set with IR Prep off. The concern is that signal inhomogeneity can result in an erroneous diagnosis.
- RECALL
GE Healthcare Precision RXi tilt joystick became stuck in the Trendelenburg direction causing the patient to slide off the table. Also recall conducted to investigate the possibility of accidentally activation of the remote console joystick where a fatal accident occurred on a non-GE Remote R&F System. .
- RECALL
GE healthcare has become aware of an artifact which could affect the diagnostic capability associated with the 3.0T Propeller T2 Flair application of the 3.0T Signa HDx scanner.
- RECALL
A software issue that may result in misregistration of functional and anatomical images associated with the 3.0T BrainwaveRT fMRI Application on the 3.0T Signa HDx scanner.
- RECALL
When a spectrum of a Pulsed Wave Doppler shows an angle correction unequal to 0 is reloaded from the archive or the image is sent to a DICOM station, this angle correction is mistakenly disregarded resulting in an underestimation of the flow velocities.
- RECALL
Incorrect patient positioning; when moving the patient into the bore may lead to wrist and hand injury.
- RECALL
When the manual cradle release feature on the table is used to move a patient out of the gantry, a discrepancy of up to 6mm between the numerical display on the gantry and the actual position of the table could be introduced.
- RECALL
Automatic exposure control (AEC) automatically resets allowing another exposure without requiring manual reset as specified in 21 CFR 1020.31 (a)(3)(iv)
