Portable X-ray units are found in most radiological/diagnostic imaging departments. They are typically exposed to a higher abuse level due to elevator openings, tight room entrances, limited patient access, and lack of space for maneuverability. This constant abuse will cause premature mechanical failure if not properly identified and corrected early. The trained service professional will be taught the skills necessary for mechanical, electromechanical, and electronic maintenance of the Shimadzu MobileArt. Each sub-system of the mechanical unit and the generator is thoroughly analyzed

Models Covered

This course will cover the following MobileArt models:

  • MobileArt Evolution
  • MobileArt Plus (MUX-100H/HJ)
  • MobileArt (MUX-100/J/E)
  • MobileArt II (MUX-100JL/101JL)

System maintenance and generator calibrations are included for the following models. Detector and digital system calibrations are not covered for the following models:

  • MobileDaRt Evolution (MUX-200D)
  • MobileDaRt (MUX-100D)


To attend this course, the service professional must have a good understanding of the principles gained through attending Phase II, or four years equivalent experience. The service professional must also possess a good mechanical aptitude.

**Students are required to bring their own manuals.


At the conclusion of this course participants will be able to:

  • Evaluate overall system performance
  • Troubleshoot mechanical and electronic problems on all components of the unit
  • Perform a complete and thorough preventive maintenance inspection on each portable unit
  • Follow circuit operations of system detail block diagrams
