ABSTRACT:
In a radiation image read-out system wherein a stimulable phosphor sheet carrying a radiation image stored therein is exposed to stimulating rays which cause it to emit light in proportion to the radiation energy stored, and the emitted light is photoelectrically read out to reproduce a visible image, preliminary read-out for detecting the radiation image is conducted by uniformly exposing the whole surface of the stimulable phosphor sheet to stimulating rays prior to final read-out, and detecting the amount of light emitted from the whole surface of the stimulable phosphor sheet. Or, preliminary read-out is conducted by exposing the stimulable phosphor sheet to stimulating rays slitwise over the entire sheet width while the slit-like exposure section is moved with respect to the stimulable phosphor sheet, and detecting the amount of light emitted from the sheet.
