What type of imaging receptor is used in computed radiography?

In computed radiography, the imaging receptor used is the photostimulable phosphor (PSP) plate. This type of plate is capable of storing and later releasing the x-ray energy it absorbs. When the PSP plate is exposed to radiation, it captures the image in a latent form. Subsequently, it undergoes a process where it is scanned by a laser in a reading device, causing the stored energy to be released as visible light. This light is then converted into a digital image.

The PSP technology allows for a flexible imaging solution that can be used in a variety of settings, providing high-quality images with lower doses of radiation compared to traditional film. This distinct process differs significantly from other types of imaging techniques like the use of digital sensors, film-screen systems, or CCD arrays, which employ different mechanisms for capturing and processing images.
