ABSTRACT:
A radiation image read-out apparatus comprises a microchannel spacial light modulator having a front surface closely contacted with a stimulable phosphor sheet carrying a radiation image stored thereon, and a stimulating ray source for irradiating nearly uniform stimulating rays simultaneously to the overall surface of the stimulable phosphor sheet from the side opposite to the microchannel spacial light modulator with respect to the stimulable phosphor sheet. A reading light source irradiates nearly uniform reading light simultaneously to the overall rear surface of the microchannel spacial light modulator after light emitted by the stimulable phosphor sheet upon exposure to stimulating rays has been detected by the microchannel spacial light modulator. A two-dimensional photodetector detects the reading light reflected and subjected to spacial modulation in accordance with the radiation image by the microchannel spacial light modulator.
