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.
Transducer element failure
MediumSymptoms: Dropout, dead elements, image banding.
Root cause: Element delamination or cable damage from repeated use.
Transducer cable / connector wear
MediumSymptoms: Intermittent image loss, connector-wiggle artifact.
Root cause: Repeated flexing and connector strain.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or storage degradation.
Display panel degradation
LowSymptoms: Dim image, color shift, dead pixels.
Root cause: Backlight or LCD panel aging.

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: Transducer element failure
- Confirm the presentation - typically dropout, dead elements, image banding - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: element delamination or cable damage from repeated use.
- 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 ultrasound transducer / probe 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.
