ABSTRACT:
In a radiation image read-out method and apparatus, a stimulable phosphor sheet carrying a radiation image stored thereon is exposed to stimulating rays which cause the stimulable phosphor sheet to emit light in proportion to the stored radiation energy, and the emitted light is photoelectrically detected by use of a light detection device to obtain image signals for use in reproduction of a visible image. Light detection ranges of the light detection device suitable for image recording conditions are stored in conformity with the respective image recording conditions in a memory. In the course of detection of the light emitted by the stimulable phosphor sheet, the image recording conditions with respect to the stimulable phosphor sheet on which image read-out is to be carried out are designated, the light detection range corresponding to the designated image recording conditions is read from the memory, and is set in the light detection device. Preliminary read-out is not used.
