摘要： An image signal representing radiation image information on an object stored on a stimulable phosphor sheet is read out by scanning the stimulable phosphor sheet with a stimulating light beam and photoelectrically detecting light emitted from the stimulable phosphor sheet upon stimulation thereof by a photodetector having a photoelectric surface. A variable transmittance medium whose transmittance to the light emitted from the stimulable phosphor sheet upon stimulation thereof is variable continuously or stepwise is inserted into the optical path of the light between the stimulable phosphor sheet and the photoelectric surface of the photodetector The transmittance of the variable transmittance medium is changed according to the amount of light emitted from the stimulable phosphor sheet upon stimulation thereof so that the photoelectric surface is not saturated by an excessive amount of light impinging thereupon.

摘要： Image processing, which is constituted of a plurality of processes, is carried out on a radiation image signal. An intermediate image signal obtained in at least one process, which is among the processes other than a last process in the plurality of the processes constituting the image processing, is stored on a predetermined storage medium. In cases where an abnormality occurred during the image processing, a process, in which the abnormality occurred, is discriminated quickly, and a cause of the abnormality is specified quickly.

摘要： In a radiation image read-out apparatus, a stimulable phosphor sheet storing thereon a radiation image is exposed to stimulating light and stimulated emission emitted from the stimulable phosphor sheet upon stimulation by the stimulating light is detected and an image signal representing the radiation image stored on the stimulable phosphor sheet is obtained by photoelectrically converting the stimulated emission. A read-out system includes an array of a plurality of read-out heads, each including a stimulating light source which projects the stimulating light onto the stimulable phosphor sheet and a photodetector which detects the stimulated emission. A conveyor system conveys the stimulable phosphor sheet and the read-out system relative to each other in a direction intersecting the direction of the array of the read-out heads.

摘要： Disclosed herein is a method of obtaining an image signal, comprising the steps of preparing an image recording sheet having a stimulable phosphor layer which emits photostimulated luminescent light in a quantity corresponding to stored energy when irradiated with stimulating light, scanning the image recording sheet in horizontal and vertical scanning directions with the stimulating light, and obtaining the image signal by detecting the photostimulated luminescent light emitted by the scanning, with a solid-state image detector having a photoconductor. The signal, output from the solid-state image detector when scanning a non-image region other than an image recording region on the image recording sheet with the stimulating light, is detected as a correction signal. A non-image component, contained in a signal output from the solid-state image detector when scanning the image recording region with the stimulating light, is suppressed with the correction signal.
