Toshiba · Model Aquilion 32
Precise Isotropic Scanning From the selections 32 x 0.5 mm or 32 x 1 mm slices a choice can be made depending on the coverage and image detail ness required. If time is critical the 1 mm slices enable the trauma department a 175 cm scan in 17 seconds with a volume reconstruction in just 2 minutes. When details are first priority for all applications isotropic resolution as fine as 0.35mm is available, showing critical details in e.g. advanced cardiac applications. Computed Volume Reconstruction, the way to go Toshiba has taken CT scanning yet another step further. With the newly introduced Volume Viewing you can scan a large volume in a minimum of time where as the Volume Viewing automatically reconstructs the scanned data into the isotropic volume used for diagnosis. No need for axial images anymore. No need to go into the data and reconstruct MPR's. Aquilion 32 uses the full quality of isotropic high resolution and has the details available to you in an instant. Volume Reconstruction also revolutionizes CT archiving. Aquilion 32 does away with the need for thin slice archiving, a problem for many IT-departments. Only the volume used for diagnosis in effect will be stored saving an enormous amount of storage space keeping the total cost of scanning as low as possible. Better results, lower exposure The highly sophisticated Toshiba Quantum denoising (patent pending) enables you to reduce patient dose up to 40%. This gives a completely new dimension to low dose scanning as Quantum denoising gives you the choice of reducing dose without loss of image quality. In addition it is the only dose reduction method offering the possibility to improve image quality at common used low dose settings. Pre-eminently the method to use for paediatric scanning. Easy to upgrade Economy of scale is the decisive factor for many administrators. Frequently faced with restricted budgets, limiting possible future expansions when extra money can be made available. The Aquilion 32 is ready for a fast and cost-effective upgrade path to Aquilion 64. This allows minimized downtime when future demand asks even more from your Aquilion 32 scanner.
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.
X-ray tube overheating / filament failure
HighSymptoms: Tube won't fire, heat-capacity alarm.
Root cause: Filament wear, cooling failure.
Cooling system fault
HighSymptoms: Tube temp alarm, duty-cycle limited.
Root cause: Pump/radiator or coolant loss.
Generator / high-voltage fault
HighSymptoms: Exposure fails, kV/mA out of range error.
Root cause: HV tank or generator board fault.
Recon / system software hang
LowSymptoms: Frozen console, acquisition timeout.
Root cause: Workstation or RAID degradation.

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.
