ABSTRACT:
A method of reading a radiographic image on a stimulable phosphor sheet includes a step of obtaining correction data in which a spatial frequency processing is conducted so as to reduce a predetermined spatial frequency component of an image information which is irradiated with radiation without placing a subject. The predetermined spatial frequency component corresponds to an irregularity with poor reproducibility in terms of its position on the image information. The correction data is made so as to eliminate an irregularity which is reproducible of its position on the image information.
