ABSTRACT:
Structural noise is accurately removed by a radiographic image correcting apparatus. A correction image data set, generated from a reference image data set obtained from a stimulable phosphor sheet onto which radiation has been uniformly irradiated, that includes at least four times the amount of structural noise compared to quantum noise, is recorded in a memory means. A correcting means corrects a radiographic image data set, employing the correction image data set recorded in the memory means.
