ABSTRACT:
Stimulable phosphor sheet comprises a plurality of stimulable phosphors which are mixed together or which take on the form of layers. The stimulable phosphors have different response speeds, with which light emission from the stimulable phosphors responds to stimulating rays which cause them to emit light in proportion to the amounts of radiation stored thereon during their exposure to radiation, and different radiation absorption characteristics which represent absorptivity with respect to energy levels of the radiation. Radiation images of an object are stored on the stimulable phosphor sheet. The stimulable phosphor sheet is then exposed to pulsed stimulating rays. Light emitted by the stimulable phosphor sheet is detected with different timings corresponding to the response speeds of the stimulable phosphors, and a plurality of image signals representing the radiation images are thereby obtained. Thereafter, subtraction processing for the radiation images is carried out on the plurality of the image signals.
