Toshiba Ultimax
Toshiba · Model Ultimax
Multipurpose Digital X-Ray Systems Made for Life Ultimax features innovative technology that supports diagnostic and interventional application versatility enhances imaging capabilities and streamlines workflow. It also features system technology to help maximize productivity through rapid positioning capabilities and multitasking operations. Advanced technologies featured on Ultimax include: Flexible tabletop design with a low table mounting position, allowing easy patient access, even for patients in wheelchairs Longest, fastest C-arm movement in the industry for rapid positioning and expanded coverage, from head-to-toe Full-range of dose management features, including unique Tantalum (Ta) filters and grid pulse fluoro, that ensure the minimum required dose while maintaining a high image quality An advanced image intensifier and sophisticated CCD camera to better visualize anatomical detail EPS-Plus, all-digital acquisition, processing and storage system providing true multitasking capabilities for faster exams and higher throughput.
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.
Fluoro dose-rate / image-brightness fault
HighSymptoms: Fluoro image too dark or bright, dose creep, ABC / ADRC not tracking.
Root cause: Image-intensifier or flat-panel degradation, or the dose-control loop.
No or inconsistent exposure / generator error
HighSymptoms: Exposure inhibited, generator error code, spot images under/over-exposed.
Root cause: HV generator / tank, tube, filament supply, or an interlock.
Table motion / tilt / spot-film device fault
MediumSymptoms: Table will not tilt or move, the spot-film / carriage will not position.
Root cause: Table drive, tilt motor, or the spot-film device drive.
Tube overload / cooling fault
MediumSymptoms: Exposures inhibited after a series, tube-heat alarm.
Root cause: Tube heat limit reached or a heat-exchanger / cooling fault.
Console / image-chain / PACS fault
MediumSymptoms: Console unresponsive, image freeze, images will not archive.
Root cause: Console PC, the image-processing chain, or the network.

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: Fluoro too dark/bright or dose creeping
- Image a phantom at a fixed field and distance and compare to baseline.
- Check the image-intensifier / detector performance via service diagnostics.
- Review the dose / ABC trend.
- Escalate an intensifier or detector degradation to the OEM.
- Re-verify dose rate against the room baseline after correction.
Symptom: Generator error / no exposure
- Record the exact generator error code.
- Confirm mains supply is within spec and all room interlocks are satisfied.
- Confirm the tube is not in a thermal lockout.
- Check the HT connections and exposure contactor.
- Escalate a confirmed HV-tank / tube fault; verify output after repair.
