Abstract: An apparatus and method for computed radiography includes a rotating laser as a pumping source for delivering light, without the use of a rotating mirror, successively to ends of each of a plurality of optical fibers arranged in an arc. Opposite ends of the optical fibers are arranged in a linear array to a previously-exposed computed radiography plate having a latent X-ray image formed thereon. The plate is moved with respect to the fibers. Light emitted from the radiographic medium due to excitation by the pumping light travels through a light guide to an optical receiver where an image signal responsive to the light intensity of the emitted light is generated. The image signal is sent to a processor to generate an image representative of the latent X-ray. An erasing of the latent x-ray image may be accomplished in the same machine apparatus that generates the representative image. Preferably, multiple erasure operations are performed with a relaxation period, e.g.

Abstract: An apparatus and method for computed radiography includes an optical pump source which may be a plurality of light emitting diodes or a movable laser. Pumping light from the optical pump source is carried through each of a plurality of optical fibers arranged in a linear array to a previously-exposed computed radiography plate having a latent X-ray image formed thereon. The plate is moved with respect to the fibers. One of a second plurality of optical fibers arranged in a linear array or a light pipe receives light emitted from the radiographic medium due to excitation by the pumping light. The second plurality of optical fibers or light pipe supplies the emitted light to an optical source, which may be a photodiode or a photomultiplier tube, where an image signal responsive to the light intensity of the emitted light is generated. The image signal is digitized and sent to a processor which generates an image representative of the latent X-ray image on the computed radiography plate.
