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
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
RF coil fault / poor SNR
HighSymptoms: Low signal-to-noise, shading, or a dead region in images; coil not detected or fails the coil check.
Root cause: Damaged RF coil element, a coil-cable / connector fault, or a preamp fault.
Gradient fault / image distortion
HighSymptoms: Geometric distortion, gradient-amplifier faults, acoustic change, over-temperature trips.
Root cause: Gradient-amplifier fault, gradient-coil cooling problem, or a gradient-coil fault.
Cryogen / cold-head / compressor fault
HighSymptoms: Rising helium boil-off, cold-head noise or stall, He level dropping, compressor alarms.
Root cause: Cold-head at end of life, a helium-compressor fault, or a chilled-water problem.
Chilled water / cooling fault
MediumSymptoms: System-cooling alarms, gradient or RF over-temperature, scans aborting.
Root cause: Facility chilled-water supply, the heat exchanger, or internal pumps.
Patient table / positioning fault
MediumSymptoms: Table will not dock, drive or index; landmarking errors.
Root cause: Table drive, docking sensor, or encoder fault.
Reconstruction / host / network fault
MediumSymptoms: Recon errors, host hangs, images will not reach PACS.
Root cause: Recon or host computer fault, or the network / storage.

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 starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Poor SNR or a dead region with one coil
- Swap in a known-good coil of the same type and repeat the scan.
- Run the coil-check / coil-QA tool.
- Inspect the coil housing and cable for damage; reseat the connector.
- Scan the ACR / QA phantom and compare SNR to baseline.
- Quarantine and exchange the faulty coil.
Symptom: Rising helium boil-off or cold-head noise
- Log the helium level and boil-off trend daily.
- Check the cold-head sound and the compressor pressures against spec.
- Confirm the chilled-water supply temperature and flow.
- Schedule a cold-head / compressor service before the level reaches the OEM action point.
- Never let the magnet approach a quench threshold - escalate urgently.

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)
