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.
Image artefacts (rings / streaks / noise)
HighSymptoms: Ring or band artefacts, excessive noise, HU non-uniformity, failed daily air/water calibration.
Root cause: Detector-channel drift or a bad detector module, a DAS fault, or air-cal / tube-output drift.
X-ray tube fault / end of life
HighSymptoms: Tube-arc errors, exposure aborts, kV/mA faults, spits, or noisy bearing; tube pulls high heat units.
Root cause: Anode / bearing wear or vacuum degradation - the CT tube is a wear item.
Gantry rotation / slip-ring fault
MediumSymptoms: Rotation faults, comms errors during rotation, brush dust, drive alarms.
Root cause: Worn slip-ring brushes, a drive-belt / bearing fault, or the data-transmission link.
Table / patient-positioning fault
MediumSymptoms: Table drifts, will not index to the correct position, height or cradle errors.
Root cause: Table drive, encoder, or brake fault.
Reconstruction / console / network fault
MediumSymptoms: Recon hangs or is slow, images will not send to PACS, console errors.
Root cause: Recon-hardware or console-PC fault, or the network / storage.
Chiller / cooling fault
MediumSymptoms: Over-temperature warnings, exposures inhibited after a series, coolant alarm.
Root cause: Chiller pump / fan, low coolant, or a blocked heat exchanger.

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: Ring or streak artefacts / failed calibration
- Run the daily air (fast) calibration; if it fails, run the full calibration set.
- Scan a uniform water phantom and review HU uniformity and noise.
- Check the tube warm-up and heat-unit status.
- Escalate a confirmed detector-channel or DAS fault to the OEM.
- Re-verify image quality with the phantom after any correction.
Symptom: Exposure aborts / tube-arc errors
- Note the exact error codes and the phase (warm-up vs scan).
- Run extended tube conditioning / seasoning.
- Review the arc-count and heat-unit trend.
- Confirm chiller operation and coolant level.
- Plan a tube replacement when arc counts climb or output drifts.
