Cost-effective 16 slices scanner supports high-tech care at a lower cost. 5.0 MHU tube configured with powerful 50 kW HV generator. 24 mm volume coverage and 0.75 mm slices enable advanced motion-sensitive applications. Advanced algorithms create impressive image quality for routine neuro, ortho and body imaging. DoseRight design delivers optimal dose efficiency without compromising image quality. Maximum patient throughput with an exceptionally compact design. Operator's console establishes an efficient environment for acquisition, reconstruction and post-processing. Remote Service package links your scanner directly to an online service center.
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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
For surview scan length more than 500mm,if the user aborts or skips the reconstructed surview, the image may have the wrong field of view (FOV). When user plans and performs subsequent clinical scan with the wrong FOV the actual start and end position may not be consistent with the planned positons.
- RECALL
Software defect: For Helical scan with ClearView function, when small arc (uninterrupted scan) occurs during scan, there will be some electromagnetic interference in the system which may affect the control signal of the flying focal spot, resulting in an incorrect flying focal spot sequence. If the system does not receive error, it would continue to complete the scan with the incorrect flying focal spot sequence, having an effect on the reconstruction of some images, resulting in image loss.
- RECALL
Software defect
- RECALL
The Firm discovered during contrast agent tracking scan, when the expected concentration of contrast agent is reached, later planned scan may be interrupted. The system must be powered down and restarted to clear the interruption error before scanning can resume.
- RECALL
It was found by R&D in April, 2014 that there was a defect in NeuViz 64 system software version 1.0.5+P09. The icons of side decubitus didn't meet the patient position description, when the scanner position was set to "Right" in the system setting - scanner options.
- RECALL
The A-plane compensator is made of Teflon which will become fragile due to X-ray exposure passing through it. The thinnest part of the compensator is subject to radiation degradation and as a result has been found to fail prematurely. Failure is indicated by pin or ring artifact in the image
