Toshiba RADREX-i
Toshiba · Model RADREX-i
The power to enhance productivity The Radrex-i is engineered to dramatically improve staff productivity and enhance patient care. Many productivity features are included standard to streamline workflow. The system utilizes two 43 x 43 cm high resolution detectors with high DQE for best image quality at the lowest dose. Radrex-i is the perfect solution to address the challenges with declining reimbursements and increasing patient volumes. Increase power The combination of a high weight capacity table, high heat capacity tube and powerful generator allows you to image larger patients more effectively. Raise productivity Automation comes standard with Radrex-i including features such as auto-tracking, auto-park, auto-collimation, advance image processing and body part mapping. Enhance efficiency A single point-of-contact workstation with easy-to-use ergonomic controls streamlines workflow and accelerates throughput. Improve patient care Tube-side access to examination controls, with an in-room image display, allows point of care decision making to improve patient care. [i]Radrex-i is perfectly adapted to chest, abdomen, extremities and skeletal examinations. In short, Radrex-i extraordinary performance leads the way to the design of all-digital radiography systems.

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.
Detector not connecting / dropped images
HighSymptoms: Panel not detected, images not received, wireless / tethered link drops mid-exam.
Root cause: Detector battery (wireless), Wi-Fi / tether cable, a docking / connector fault, or detector electronics.
Image quality / calibration fault
MediumSymptoms: Fixed-pattern artefacts, non-uniformity, dead pixels / lines, calibration overdue or failing.
Root cause: Detector gain / offset calibration, a bad pixel map, or physical detector (drop) damage.
Generator / exposure fault
HighSymptoms: Exposure inhibited, kV / mAs error, no exposure captured, AEC over/under.
Root cause: HV generator, tube, filament supply, or an AEC / interface fault.
Positioner / tube-stand / bucky fault
MediumSymptoms: Tube column, wall stand or table bucky will not track, detent, or auto-position.
Root cause: Drive motor, brake, encoder, or the auto-positioning interface.
Acquisition workstation / PACS fault
MediumSymptoms: Images will not display, process or send; worklist missing; slow processing.
Root cause: Workstation PC, software, or the DICOM / network configuration.

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: Detector not connecting or images not arriving
- Check the detector battery (wireless) or reseat the tether.
- Confirm the Wi-Fi access point, channel and range.
- Reboot the detector and the acquisition workstation.
- Try a known-good detector if the site has one.
- Escalate a confirmed detector-electronics fault to the OEM.
Symptom: Fixed-pattern artefacts or failed calibration
- Run the detector gain / offset calibration and the dead-pixel map.
- Inspect the detector for drop / crush damage.
- Expose a uniform phantom and check uniformity.
- Confirm the generator and AEC are within spec with an analyser.
- Exchange the detector if calibration will not hold.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
It was discovered during a procedure that when the operator made an exposure on the wireless x-ray detector and the image data was sent to the digital radiography system, and error message was displayed " System Error (2063)" which required a reboot and loss of the image.
- RECALL
It has been found that some of the starter cables used for x-ray tube high speed rotation are not sufficiently durable.
- RECALL
Toshiba America Medical Systems Inc (TAMS) has initiated a field correction on the DRAD-3000E; Radrex-I, Electrostatic x-ray imaging system due to a software bug that results in a loss of image.
