Advanced Fluoroscopic System Maintenance (Phase 3)


Advanced Fluoroscopic System Maintenance is a formal hands-on course that provides a comprehensive approach to servicing fluoroscopic and vascular imaging systems. Emphasis is placed on system performance and image evaluation. Each subcomponent of the imaging system is thoroughly analyzed, and methods of optimizing system performance are applied.

Participants perform complete system alignment and calibration while evaluating each sub-component for its specific modulation transfer function. Participants also have the opportunity to troubleshoot all phases of the imaging system chain.


To attend this course, the service professional must have good fundamental knowledge of radiological physics and procedures as taught by our Principles of Servicing Diagnostic X-Ray Systems (Phase 1) course, or two years equivalent experience.


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

  • Perform complete calibration on fluoroscopic imaging systems
  • Evaluate overall performance of imaging system components
  • Troubleshoot imaging problems on all components of the imaging chain
  • Use proper test equipment to evaluate system performance
  • Perform complete CDRH testing of the imaging system
  • Perform complete CDRH compliance tests on the system
