Advanced Digital Imaging System Maintenance (Phase 3)

Overview

Advanced R&F, & Digital FPD System Maintenance is a formal hands-on course that provides a comprehensive approach to servicing today’s digital fluoroscopic, surgical C-Arms, cardiac, and vascular imaging systems. Emphasis is placed on system performance and image evaluation. Each sub-component 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 digital imaging performance. Participants also have the opportunity to troubleshoot all phases of the imaging system chain.

Prerequisites

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.

Objectives

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

  • Perform complete calibration on CArms and digital fluoroscopic imaging systems
  • Perform complete calibration on various digital FPD (Flat Panel Detector) systems
  • Evaluate overall performance of digital imaging system components
  • Toubleshoot imaging problems on all components of the imaging chain
  • Use proper test equipment, software, procedures, and phantoms to evaluate system performance
  • Evaluate different methods for performing system ghosting and cloning procedures
  • Determine and perform suitable ghosting and cloning procedures, as they pertain to specific systems
