ABSTRACT:
In a radiation image recording and read-out system in which a radiation image is once recorded on a recording material comprising a stimulable phosphor layer, the recording material is then scanned with a laser beam, and light emitted from the recording material is photoelectrically read out to reproduce a visible image, a gas ion laser beam having a wavelength shorter than 600 nm is employed as the laser beam. The recording material is fixed on a supporting material, circulated and reused to record radiation images thereon. The apparatus comprises a mechanism for circulating the recording material with respect to the image read-out section by repeatedly moving the supporting material and the image read-out section with respect to each other, and an erasing apparatus for eliminating the radiation energy remaining in the recording material after the read-out step. The supporting material is an endless belt, a rotatable drum or a plate, and the recording material is a continuous phosphor layer or a phosphor sheet.
