METHOD AND APPARATUS FOR RADIOGRAPHIC IMAGING

摘要

An apparatus and method for computed radiography includes an optical pump source (216), which may be a plurality of light emitting diodes or a movable laser (234). Pumping light from the pump source (216) is carried through each of a plurality of optical fibers (218) arranged in a linear array to a previously-exposed radiography plate (212) having a latent X-ray image formed thereon. The plate (212) is moved with respect to the fibers. One of a second plurality of optical fibers arranged in a linear array (220) or a light pipe receives light emitted from the radiographic medium due to excitation by the pumping light and supplies the light to an optical receiver such as a photodiode or a photomultiplier tube (222) where an image signal responsive to the light is generated. The signal is digitized and sent to a processor which generates an image representative of the latent X-ray image.
