OrthoScan Mobile DI
OrthoScan · Model Mobile DI
OrthoScans new mini c-arm with flat detector offers surgeons increased image quality, a smaller thin design, improved reliability, and more efficient imaging. Once again OrthoScan is setting the new standard in mini c-arm imaging.
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.
No or inconsistent fluoro / exposure
HighSymptoms: No image on boost, exposure inhibited, kV/mA error, image too dark or bright.
Root cause: X-ray tube / monoblock fault, HV generator fault, or the AEC / dose-control loop.
Image-intensifier or flat-panel detector fault
HighSymptoms: Dim, distorted, vignetted or noisy image; dead lines (flat panel); S-distortion (II).
Root cause: Image-intensifier tube ageing / II fault, or a flat-panel detector fault.
C-arm movement / brake fault
MediumSymptoms: Orbital, lateral or vertical motion binds, drifts, or a brake will not hold.
Root cause: Worn friction brakes, bearings, or the counterbalance.
Monitor cart / video fault
MediumSymptoms: No image on one or both monitors, image freeze, no last-image-hold.
Root cause: Monitor, the cart-to-stand cable, or the image-processing PC.
Thermal / duty-cycle lockout
LowSymptoms: Fluoro inhibited after a run, tube-heat warning.
Root cause: Monoblock heat limit reached or a cooling-fan fault.

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: No or poor fluoroscopic image
- Note the exact error and whether it is dose (dark/bright) or geometry (distortion).
- Confirm the tube is not in a thermal lockout.
- Check the interconnect cable between the stand and the monitor cart.
- Run any built-in image-calibration / gain routine.
- Escalate a confirmed tube, II or detector fault; verify output with an X-ray analyser after repair.
Symptom: C-arm motion binds or a brake slips
- Identify which axis (orbital / lateral / vertical / wig-wag).
- Check the brake handle / lock and its cable or solenoid.
- Inspect the bearings and counterbalance for that axis.
- Adjust or replace the friction-brake kit.
- Confirm smooth motion and that each brake holds under load.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Ziehm Imaging, Inc., distributor, have been informed by manufacturer, Ziehm Imaging GmbH that installed devices may not fully meet the requirements of IEC 60601-2-54 and or 21 CFR 1020.32(c) with respect to wired hand switch may fail when being exposed to mechanical stress such as shocks (e.g. dropping) or impacts can irreversibly damage the switching element in the hand switch. A defective switching element may then potentially initiate unintended radiation of the connected mobile X-ray unit.
- RECALL
OrthoScan Inc. discovered during investigation of a non-standard work flow a non-conformity of the devices. Specifically, the system software allows a user to activate the Digital Zoom feature in the course of taking a live image exposing a larger x-ray field than can be viewed by the user
