Phase-I-Course-Outline

Introduction

Principles of Servicing Diagnostic X-Ray Systems is a skills development program that teaches the new service professional the cognitive skills necessary to understand the X-ray system and its applications in the medical community. The program is divided into six major learning units:

  • Introduction to radiography
  • Radiation safety
  • The production of X-rays
  • Formation of the X-ray image
  • Image receptor technologies
  • PACS troubleshooting basic

The course contains lecture, demonstration, and hands-on training, which teach participants proper operation, radiation safety, image quality assessment, and global understanding of the X-ray system. Upon completion of the course, the student will be able to perform first level service on the radiographic system.

Prerequisites

To attend this course, the service professional must have a two year associate degree in electronics or equivalent service experience.
