Abstract:
A two-side radiation image reading method comprising the steps of scanning a stimulable phosphor sheet having a radiation image recorded thereon, photoelectrically detecting light emitted from the front and back sides of the sheet by using photoelectric reading means separately located on the front and back sides of the sheet to read two image signals representing the radiation image, and obtaining a final image by carrying out addition processing on the two image signals, the radiation image reading method further including the steps of acquiring shading correction and/or fading correction data in advance and carrying out shading correction and/or fading correction on the image signals by using the shading correction and/or fading correction data having been obtained,wherein correction is carried out for images only on the front side or the back side of stimulable phosphor sheets by applying shading correction and/or fading correction data for the image after addition processing so that uniformity of the images after addition can be retained.
