RADIATION IMAGE RECORDING AND READ-OUT APPARATUS

摘要

A radiation image recording and read-out apparatus comprises an image recording section for recording a radiation image of an object on a stimulable phosphor sheet, a read-out section for scanning the stimulable phosphor sheet by stimulating rays and for detecting the light emitted thereby upon stimulation, and an erasing section for releasing the radiation energy remaining on the stimulable phosphor sheet. The stimulable phosphor sheets are circulated through these sections and reused for image recording. A radiation stop device is positioned at the image recording section for defining the radiation exposure area on the stimulable phosphor sheet. Information on the radiation exposure area is stored in a storage device for each stimulable phosphor sheet. On the basis of this information, the area of scanning by the stimulating rays in the read-out section is controlled so that the scanning is conducted approximately over the radiation exposure area.
