Toshiba AQUILION PRIME 302
Toshiba · Model AQUILION PRIME 302
X-ray tube voltage (kV)80-135 Number of slices 160 Full 360° scan time (sec)0,35 Minimum scan time (sec)35 Scan fields of view (mm)200
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.

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.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Toshiba American Medical Systems (TAMS) is recalling the Aquilion CT system because it has been reported that the cooling oil in the x-ray tube heat exchanger may leak during system operation.
- RECALL
It has been found that if the scan range extends beyond the maximum Field of View (FOV), a reconstruction operation error may occur. As a result, scanning may be interrupted and rebooting of the system may be necessary. Please note that this issue has not occurred in the U.S.
- RECALL
Toshiba American Medical Systems, Inc. is recalling the TSX-035A because of a potential problem with the Aquilion Lightning CT System iStation cover falling off of the gantry.
- RECALL
If two specific operations are performed in multi-phase helical scanning, the acquired raw data may not be saved.
- RECALL
Potential problem with the cardiac function analysis software (CFA). Incorrect analysis results may be displayed in the Function Parameters for the Entire Heart displayed as analysis results of the CFA and in a Left-Ventricular Volume Curve generated based on some of those parameters.
- RECALL
Toshiba America Medical Systems, Inc. initiated this recall due to the failure of the parts used in the X-ray high-voltage generator. In some cases, X-ray exposure cannot be performed.
- RECALL
Toshiba intitiated this recall because their investigation revealed that due to a problem of the X-ray output control software, the X-ray output conditions may not be set correctly. As a result, X-ray exposure under the scan conditions used for contrast study may not start.
- RECALL
The recall was initiated because Toshiba has confirmed that their is a potential software issue for the TSX-301A Aquilon One and the TSX-301B Aquilon One.
- RECALL
The firm initiated this recall due to a potential software issue. The DLP (Dose Length Product) value may be displayed incorrectly when the vHP option is used.
- RECALL
Toshiba America Medical Systems is initiating a field correction on their TSX-301B: AQUILION Premium; System, X-Ray, Tomography, Computed, TSX-301A: AQUILION One; System, X-Ray, Tomography, Computed, TSX-20IA: AQUlLlON LB; System, X-Ray, Tomography, Computed, and TSX-1O1A: AQUILION 16; System, X-Ray, Tomography, Computed due to several software issues that cause the scanners to function incorr
- RECALL
Toshiba America Medical Systems (TAMS) is initiating a field correction for the TSX-301A and TSX-301B: Aquilion 64 System, X-Ray, Tomography because communication between reconstruction units in the system console may be broken due to failure of the optical conversion connector, resulting in a break of communication between units.
- RECALL
There is the potential that the current may not be controlled correctly in examinations using the ECG modulation function, which adjusts the x-ray output in synchronization with the ECG waveform.
- RECALL
Incorrect Dose Calculation. The software that performs the pre-scan dose calculation uses an incorrect parameter for an exam Plan using a tube voltage of 80kV or 100kV. This results in a pre-scan expected dose that is approximately 10% lower than what the displayed value should be when the scanner executes the exam Plan.
- RECALL
Toshiba America Medical Systems (TAMS) has found that communication may be cut off in the Aquilion ONE/ Premium Systems, owing to the failure of a part used in the console.
- RECALL
The recall was initiated by Toshiba America Medical Systems (TAMS) because the software associated with TSX-101A: Aquilion 64 can prevent scanning from being performed at the specified helical pitch (couch movement speed).
- RECALL
When W-Volume is performed in Prospective CTA or Target CTA studies with ECG gating, unnecessary intervals may be set before starting the volume scan. As a result, scanning cannot be performed at the appropriate timing of constant enhancement and clinically useful images may not be obtained.
- RECALL
ECG Gated Dynamic Volume Prospective scan may stop if preset eXam Plan is confirmed and CTA On is changed to CTA OFF, due to exposure control PWB.
- RECALL
Toshiba America Medical Systems Inc (TAMS) has initiated a field correction on the Aquilion 32 CT Scanners due to the potential for the bolus tracking software (SureStart) to cause delay of the helical scan, up to 10 seconds, when large volumes of data are being reconstructed on the secondary console.
- RECALL
The SureStart function may not operate in the usual manner, and you may obtain abnormal analysis results when using the cerebral blood flow analysis function.
- RECALL
The systems all have a similar table control board. It has been found that this board may cause the table position to be incorrect if the table cradle is moved manually. This is referred to as "Free" mode in the operation manuals. If this error does occur it is possible that the patient could be scanned at an incorrect position.
- RECALL
Excessive radiation: Intermittent shifting of CT numbers causes the actual dose to the patient to be greater than expected, when Sure Exposure option is used.
