Abstract:
A radiation image information read-out method, comprising the steps of:i) exposing a stimulable phosphor sheet, on which radiation image information has been stored, to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, ii) detecting light emitted from opposite surfaces of the stimulable phosphor sheet when the stimulable phosphor sheet is exposed to the stimulating rays, two original image signals representing the radiation image information being thereby acquired, and iii) performing operation processing on the two original image signals and in accordance with predetermined operation processing parameters, an operation-processed image signal, which represents the radiation image information, being thereby obtained, wherein a ratio between read-out sensitivities with respect to the opposite surface sides of the stimulable phosphor sheet and/or the predetermined operation processing parameters with respect to at least either one surface side of the stimulable phosphor sheet are controlled in accordance with read-out conditions employed at the time of the image signal acquisition.
