Shimadzu MobileDaRt Evolution EFX
Shimadzu · Model MobileDaRt Evolution EFX
Low chassis height ensures excellent forward vision. Drive away immediately; no waiting around for the PC to boot-up before drive is possible. SSD for very fast PC / DR system boot-up time. With battery powered drive, integral independent drive motors, along with sensitive steering & speed enable effortless and accurate positioning of the MobileDaRt in confined spaces. The tube support column rotates 270o and the ergonomic telescopic arm allows smooth, fast positioning of the X-ray tube. The ‘Inch mover’ facility allows fine tuning of the unit’s position from the tubehead. The optional second exposure switch allows the radiographer to acquire an image when they are positioned remotely to the trolley or bed. Optional Keyless Entry with 10 different passwords customises individual user setup and protocols and means no more lost keys. Optional wireless remote handswitch allowing collimator and exposure activation. Back-up detector cable if wireless communication is not possible or is blocked.
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: No or inconsistent exposure
- Note the exact error code.
- Confirm the battery bank is fully charged (exposure energy depends on it).
- Check the exposure switch and cable.
- Confirm the tube is not in a thermal lockout.
- Escalate a confirmed generator / capacitor / tube fault; verify output with an analyser after repair.
Symptom: Will not drive or short battery life
- Check the charge level and that the charger reaches full charge overnight.
- Load-test or check the battery bank voltages against spec.
- For no-drive, check the drive fuse, motor controller and throttle.
- Replace the battery bank when capacity is low.
- Confirm exposure count per charge returns to spec.

Documents & Manuals
Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
There is a potential that the adjustable handle option on the X-Ray system may have been installed with improper bolts. This could result in improper driving operation which could lead to harm of individuals around the device.
- RECALL
In these units, the brake is usually released by gripping the drive handle and applied by letting go of the handle. However, for systems within a specified manufacture period, we have identified that even when letting go of the handle, the systems brakes are not applied. In this event, if the Operator releases the handle when the device is moving, the unit will continue to coast.
- RECALL
The firm is recalling the Shimadzu Mobile X-ray system because an image may not transfer to image server properly.
