X-Ray Generators, Tubes & Exposure Control

Syllabus

# XRY 110 - X-Ray Generators, Tubes & Exposure Control

## Course Description
This course provides a comprehensive study of X-ray generator topologies, including high-frequency and capacitor discharge systems, essential for the biomedical equipment service technician. Students will gain in-depth knowledge of X-ray tube construction, heat units, and rating charts, crucial for safe and effective operation. The curriculum covers automatic exposure control (AEC) circuit theory, calibration procedures for kilovoltage peak (kVp), milliamperage (mA), and exposure time, and critical tube conditioning protocols. Emphasis is placed on understanding the interdependencies of these components to diagnose and repair common failures. Practical applications include simulated bench work and field service procedures, ensuring graduates are prepared for real-world challenges in diagnostic X-ray system maintenance and repair. Safety protocols and regulatory compliance are integrated throughout the course.

## Learning Outcomes
Upon successful completion of this course, students will be able to:
* Identify and describe the functional blocks and operational principles of various X-ray generator topologies.
* Analyze X-ray tube construction, understand heat unit calculations, and interpret tube rating charts for safe operation.
* Explain the theory and operation of Automatic Exposure Control (AEC) circuits and their role in image quality.
* Perform calibration procedures for kVp, mA, and exposure time on diagnostic X-ray systems.
* Execute X-ray tube conditioning and warm-up protocols to extend tube life and ensure consistent performance.
* Troubleshoot common faults in X-ray generators, tubes, and exposure control systems using vendor-neutral diagnostic techniques.
