    摘要: A radiation image read-out apparatus is constituted for exposing a recording material provided with a stimulable phosphor and carrying a radiation image stored thereon to stimulating rays which cause the recording material to emit light in proportion to the stored radiation energy, and photoelectrically detecting the emitted light to read out the radiation image. The apparatus is provided with a multi-layer optical filter whose reflectivity with respect to stimulating rays increases as the angle of incidence of stimulating rays increases. The multi-layer optical filter is disposed in the optical path of stimulating rays in the vicinity of the recording material or formed on the surface of the recording material on the stimualting ray irradiation side, thereby increasing the efficiency of utilization of stimulating rays. In one embodiment, a second multi-layer optical filter is disposed in the vicinity of or formed on the surface of the recording material on the emitted light detection side. The second filter substantially reflects stimulating rays and substantially transmits the emitted light.

    摘要: A radiation image read-out apparatus comprises a linear stimulating ray source for emitting stimulating rays to a linear portion of a stimulable phosphor sheet carrying a radiation image stored therein, and a line sensor constituted by many solid state photoelectric conversion devices. The line sensor extends at least over the length of the linear portion of the stimulable phosphor sheet exposed to stimulating rays. Light emitted by the linear portion of the stimulable phosphor sheet upon stimulation thereof is received and photoelectrically converted by the solid state photoelectric conversion devices. The portion exposed linearly to stimulating rays and the line sensor are moved with respect to the stimulable phosphor sheet, and outputs of the line sensor are sequentially read out in accordance with the movement of the portion exposed linearly to stimulating rays and the line sensor with respect to the stimulable phosphor sheet.
