Abstract
In a radiographic image recording system in which a stimulable phosphor plate is exposed to X-rays to record a radiographic latent image therein, the stimulable phosphor plate is exposed to stimulating rays thereafter to emit light according to the stored energy of X-rays, and the emitted light is detected by a photodetector and converted to an image signal to be used for finally recording a visible image on a photosensitive film or the like, a plurality of stimulable phosphor plates are used for recording radiographic images of an object viewed from the same direction. The image signals read out from the plurality of stimulable phosphor plates are superposed to obtain an averaged image signal. The averaged image signal is then subjected to a gradation process for enhancing the contrast of the image.
