# XRY 120 - Calibration, Quality Assurance & Preventive Maintenance

**Credits:** 3

**Term:** 3

## Course Description

This course provides comprehensive training in the calibration, quality assurance, and preventive maintenance of diagnostic X-ray equipment. Students will master essential procedures for ensuring optimal performance, patient safety, and regulatory compliance. Key topics include kVp and mAs accuracy testing, half-value layer determination, timer and automatic exposure control (AEC) verification, and collimator and beam alignment assessments. The curriculum emphasizes the selection and proper use of specialized test tools, development of robust preventive maintenance schedules, and adherence to industry best practices. This course is critical for technicians responsible for maintaining high standards in X-ray imaging facilities.

## Learning Outcomes

Upon successful completion of this course, students will be able to:

*   Accurately measure and evaluate X-ray tube voltage (kVp) and tube current-time product (mAs) for diagnostic systems.
*   Perform half-value layer (HVL) measurements to assess beam quality and filtration, ensuring compliance with radiation safety standards.
*   Test and verify the accuracy of X-ray exposure timers and automatic exposure control (AEC) systems.
*   Conduct collimator light field and X-ray beam alignment checks, identifying and correcting discrepancies.
*   Select, operate, and calibrate specialized test equipment required for X-ray system performance evaluation.
*   Develop and implement comprehensive preventive maintenance schedules and quality assurance protocols for diagnostic X-ray units.
