# XRY 115 - Image Receptors, Digital Radiography & Detectors

## Course Description
This course provides a comprehensive study of image receptors and digital radiography detectors used in diagnostic X-ray systems. Students will learn the fundamental principles, construction, and operation of Computed Radiography (CR) and Digital Radiography (DR) systems, including flat-panel detectors. Emphasis is placed on understanding the digital image chain, identifying and troubleshooting common artifacts, and performing essential detector calibration procedures. Successful completion ensures technicians are prepared to service and maintain modern X-ray imaging systems safely and effectively.

## Learning Outcomes
Upon successful completion of this course, students will be able to:
* Explain the fundamental principles of Computed Radiography (CR) and Digital Radiography (DR) image acquisition.
* Identify the key components and operational characteristics of various flat-panel detector technologies.
* Trace the digital image chain from X-ray exposure to image display, identifying potential points of failure.
* Diagnose and troubleshoot common image artifacts associated with CR and DR systems.
* Perform routine calibration and quality assurance procedures for digital radiography detectors.
