    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： In a radiation image read-out apparatus, a stimulable phosphor sheet, on which a radiation image of an object has been stored, is scanned with a laser beam of a predetermined output power, which causes the stimulable phosphor sheet to emit light in proportion to the amount of energy stored thereon during its exposure to radiation, and the emitted light is photoelectrically detected with a predetermined sampling time. A response speed r �sec! of the stimulable phosphor constituting the stimulable phosphor sheet, the laser beam output power p �W!, a picture element size s �m!, and the sampling time t �sec! are set such that they may satisfy Formulas (1), (2), and (3): r/(s.multidot.t) 1 (3) The radiation image having been stored on the stimulable phosphor sheet is thereby read out quickly and such that a reproduced image having good image quality may be obtained.
