The imaging receptor (IR) system is composed of which two components?

The imaging receptor (IR) system is essential in capturing the X-ray images as it is responsible for detecting the X-rays that pass through the patient's body. The two components of the IR system are the cassette and the phosphor plate.

The cassette serves as the container that holds the phosphor plate, which is the actual imaging medium. The phosphor plate is sensitive to radiation and will store the energy from the X-rays, which can be later processed to create a diagnostic image. This combination effectively captures the image by converting X-ray photons into a form of energy that can be processed for visual examination.

The other options do not accurately describe the components of the imaging receptor system. The detector and darkroom indicate different phases of imaging processes; the x-ray tube and control booth pertain to the production and control of X-ray exposure, and film and developer refer to traditional film-based imaging, which is now less common in favor of digital systems. Hence, the focus on the cassette and phosphor plate reflects an understanding of modern imaging technologies and their crucial roles in the X-ray imaging process.
