Where is the latent image stored during computed radiography (CR) until it is processed?

In computed radiography (CR), the latent image is stored in a photostimulable phosphor plate. When an x-ray exposure is made, the plate, which contains a material that can absorb and store x-ray energy, captures the image. This stored energy forms what is known as a latent image.

During the processing phase, the photostimulable phosphor plate is stimulated by a laser beam, which causes it to release the stored energy in the form of light. This light is then detected by a sensor and converted into a digital image for further analysis. The specific nature of the photostimulable phosphor is crucial because it enables this unique storage mechanism, distinguishing it from traditional film-based imaging or other digital methods.

Other options do not accurately describe where the latent image resides prior to processing. For instance, the imaging plate refers more broadly to any plate used for imaging, while a computer hard drive is used for storing processed images rather than the latent image itself. X-ray film, on the other hand, is part of traditional radiography and does not incorporate the principles of computed radiography.
