Course Outline
Advanced Diagnostic Imaging System Analysis (Phase 4)
Overview
This course is designed to provide the service professional with the skills and knowledge necessary to restore an X-ray imaging system to optimum performance after replacing the system glassware. This will include hands on installation and calibration of the X-ray tube, the image intensifier, the photo multiplier tube, the TV camera tube and CRT of the monitor. The course will conclude with a discussion of customer satisfaction skills.
Prerequisites
To attend this course, the service professional must have good fundamental knowledge and understanding of the principles gained through attendance at our Phase 1, Phase 2, and Phase 3 X-ray courses or equivalent field experience.
Objectives
At the conclusion of the course, participants will be able to:
- Use proper test procedures to determine the need for glassware replacement
- Select the proper glassware for application
- Perform proper de-installation procedures
- Perform proper pre-installation inspections
- Perform proper installation procedures
- Perform the calibration procedures necessary to restore the system to optimum performance
- Perform the necessary compliance tests
- Complete all necessary paperwork
- Apply the appropriate customer satisfaction skills for opening and closing the service call
