Abstract
A radiation image read-out apparatus comprises a system for scanning a stimulable phosphor sheet carrying a radiation image stored thereon with stimulating rays in a main scanning direction, a system for moving the stimulable phosphor sheet with respect to the stimulating rays in a sub-scanning direction, and a photodetector for detecting light emitted by the stimulable phosphor sheet when it is exposed to stimulating rays. A stored energy signal output device receives information on the level of radiation energy stored on the stimulable phosphor sheet, and generates a signal corresponding to the information. The radiation dose at image recording is used to provide the information on the level of stored energy. A stimulation energy adjuster receives the signal generated by the stored energy signal output device, and adjusts the level of stimulation energy of stimulating rays per unit area of the stimulable phosphor sheet based on the signal.
