ABSTRACT:
The radiation image of a subject such as a human spine is recorded on and read from a stimulable phosphor sheet which is circulated in a radiation image recording and reading apparatus. The stimulable phosphor sheet with the radiation image recorded thereon is fed to an image reading unit in which stimulating light is applied to the stimulable phosphor sheet to cause the stimulable phosphor sheet to emit light representative of the recorded radiation image. Then, the stimulable phosphor sheet is fed to and past an erasing unit, which applies erasing light to the stimulable phosphor sheet to erase any residual radiation image information from the stimulable phosphor sheet in the erasing unit, while feeding the stimulable phosphor sheet back past the erasing unit. The stimulable phosphor sheet is held in readiness for recording another radiation image thereon after the residual image information has been erased, and thereafter, the stimulable phosphor sheet is fed to an image recording unit.
