Shimadzu MobileArt Evolution MX7
Shimadzu · Model MobileArt Evolution MX7
Reduced exposure time for better image quality One-touch setup of radiography conditions Shock-resistant body design Clear illuminated indication of exposure timing Keyless access Emergency radiography even when the battery is low.
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 exposure
HighSymptoms: Exposure inhibited, kV / mAs error, images under- or over-exposed.
Root cause: HV generator / capacitor fault, exposure-switch fault, tube fault, or a thermal interlock.
Drive / propulsion fault (motor-driven units)
MediumSymptoms: Unit will not drive, drives weakly, or a drive fault code.
Root cause: Drive battery, drive motor / controller, or the throttle handle.
Battery pack will not hold charge
HighSymptoms: Few exposures per charge, will not reach full charge, unit dies mid-round.
Root cause: Aged exposure / drive battery bank or a charger fault.
Column / arm / brake fault
MediumSymptoms: Tube arm drifts, will not extend / rotate, or a brake will not hold.
Root cause: Worn arm bearings, counterbalance, or brakes.
Detector / console fault (DR units)
MediumSymptoms: Panel not detected, images not received, console errors.
Root cause: Wireless detector, its battery, or the acquisition PC.

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 / images not received / link drops
- Check the detector battery charge (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 / non-uniformity / dead pixels or lines / 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 X-ray analyser.
- Exchange the detector if calibration will not hold.
Symptom: No or inconsistent exposure / generator error / kV-mAs inaccuracy
- Note the exact generator error / fault code.
- Confirm the mains supply is within the generator's spec (line-voltage compensation).
- Check the HT cables and the exposure contactor.
- Confirm the tube is not in a thermal lockout.
- Escalate a confirmed inverter / HV-tank / tube / filament fault; verify output with an analyser after any repair.
Symptom: AEC (phototimer) images consistently over- or under-exposed
- Verify the AEC response with a phantom at two thicknesses.
- Check the AEC chamber connections and the selected chambers / density.
- Recalibrate the AEC per the service procedure.
- Compare against a manual technique.
- Replace the AEC chamber if it will not calibrate.
Symptom: Tube stand / table / wall bucky will not track, detent or auto-position
- Check the drive, brake, detents and counterbalance for that axis.
- Inspect the position encoder / potentiometer.
- Check the auto-positioning interface and cabling.
- Adjust or replace the brake / drive hardware.
- Confirm smooth motion and reliable detents / SID.

- RECALL
The recall was initiated because Shimadzu Corporation has identified a potential issue in certain manufacturing lots of the Shimadzu MobileDaRt Evolution in combination with CXDI-70C, CXDI-55C, and CXDI-55G. As a result of Shimadzu's investigation, there is a potential risk for screws becoming loose inside the Shimadzu Mobile X-ray systems.
