Toshiba TSX- 003A
Toshiba · Model TSX- 003A
CT Scanner The TSX-003A by Toshiba provides patients with a unique and comprehensive exam. This scanner is one of the most advanced CT scanners on the market. With this scanner, you will be to reduce your diagnosis time down to just minutes.
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
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
Due to a problem with the control software of the x-ray high-voltage generator, if scanning is performed with a tube current less than 30mA, the control software may detect an error and perform error processing even though the x-ray output is normal.
- 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.

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
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.
