Toshiba Aquilion Super 4
Toshiba · Model Aquilion Super 4
Boldly setting the standard for everyday, 1/2-second high-speed scanning, Aquilion Super 4 improves temporal and spatial image resolution with longer, faster helical scanning for thinner slice, 3D volume imaging. An improved X-ray tube and an incredibly versatile detector array complement this supercharged CT scanner, giving it superior uptime performance and true isotropic imaging capabilities. Advances featured on the Aquilion include: Selectable Slice Multi-row Detector for optimal slice thickness combinations and unique "Quad" slice design for true 0.5 mm resolution at eight slices per second. MegaCool X-ray tube, with 7.5 MHU heat capacity available for uptime reliability. SURETechnologies like the SUREStart, SUREFluoro, and SUREExposure for improved dose management and more precise CT interventional procedures. Intuitive user features, such as a multitasking console and workstation to make scanning and image processing faster and easier.
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.
Power supply fault
MediumSymptoms: Unexpected shutdown, unit won't power on.
Root cause: PSU or backup battery aging.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or storage degradation.
Network / DICOM connectivity fault
MediumSymptoms: Images fail to transfer, PACS timeout.
Root cause: Network configuration or interface card fault.

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: X-ray tube overheating / filament failure
- Confirm the presentation - typically tube won't fire, heat-capacity alarm - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: filament wear, cooling failure.
- 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 x-ray tube insert 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: Detector calibration drift
- Confirm the presentation - typically image noise, artifacts, low SNR - and note the exact alarm or message and the conditions when it occurs.
- Check the most likely cause first: flat-panel / sensor aging.
- 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 flat-panel detector 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.
