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.
