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.
Ultrasound transducer / probe wear
HighSymptoms: Inaccurate volume readings, or no image.
Root cause: Transducer element or cable wear.
Battery / charging fault
MediumSymptoms: Won't hold charge, shuts down mid-scan.
Root cause: Aged rechargeable battery pack.
Aiming / positioning calibration drift
MediumSymptoms: Scan targets wrong anatomy, inaccurate volume.
Root cause: Internal aiming-icon calibration drift.
Display / touchscreen fault
LowSymptoms: Unresponsive controls, frozen screen.
Root cause: Touchscreen digitizer or display 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: Ultrasound transducer / probe wear
- Confirm the presentation - typically inaccurate volume readings, or no image.
- Check the most likely cause first: transducer element or cable wear.
- Inspect the affected subsystem against the manufacturer's inspection checklist.
- If the fault is confirmed and not a field adjustment, service or replace the ultrasound transducer / probe head 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.
Symptom: Aiming / positioning calibration drift
