摘要： In a radiation image recording and read-out apparatus, stimulable phosphor sheets are circulated along a predetermined circulation path through an image recording section for recording a radiation image of an object on the stimulable phosphor sheet by exposing the stimulable phosphor sheet to radiation through the object, an image read-out section including a stimulating ray source which is disposed in the circulation path and emits stimulating rays for scanning the stimulable phosphor sheet and a photoelectric converter which receives light emitted from the stimulable phosphor sheet to obtain an image signal and an erasing section for releasing residual radiation energy in the stimulable phosphor sheet before the stimulable phosphor sheet is returned to the image recording section. A cleaning sheet having thereon an adhesive material layer is transferred along the circulation path.

摘要： A stimulable phosphor sheet, on which a radiation image of an object has been stored, is exposed to stimulating rays, which cause the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation. The emitted light is detected by a photoelectric read-out device, and an image signal representing the radiation image is thereby obtained. Threshold value processing is carried out in accordance with the obtained image signal, and a prospective abnormal pattern is thereby detected from the radiation image. A predetermined threshold value, which is used in the threshold value processing for detecting the prospective abnormal pattern, is set to be a small value as the amount of change in the image signal corresponding to the region in the vicinity of the prospective abnormal pattern becomes large.

摘要： 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.
