How does Computed Radiography (CR) work?
The phosphor plates in their cassettes are exposed to the x-ray the same way as film. During exposure the x-ray radiation is absorbed in the phosphor plate forming a latent image. The latent images are “extracted” from the plates when a laser beam generated inside the reader illuminates the phosphor plate. The laser beam provides enough energy to reverse the latent image formation process causing the plates to emit photons of light. The photons are detected and translated into an image that can be enhanced, processed and displayed on the monitor. • How many times can I reuse a phosphor plate? The phosphor plate forms and stores temporary latent images of an incoming x-ray. A plate can be erased and reused virtually indefinitely. Plates can be used in a lighted room and are protected from exposure to scratches, fingerprints and dirt. • Is a Computed Radiography (CR) system easy to use? Intuitive interface of the system allows for a short learning curve, easy access to all of the feature
