Abstract
In a radiation image recording system in which a radiation image is once recorded on a stimulable phosphor and then read out to reproduce a visible radiation image, at least one recording material formed of a phosphor layer and fixed on a supporting material is circulated and reused to record radiation images thereon. The system 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 on 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.
Claims10
A radiation image recording and read-out system comprising:
- (a) a supporting material,
- (b) at least one recording material fixed on said supporting material and comprised of a stimulable phosphor layer capable of storing a radiation image,
- (c) an image recording section for exposing said recording material to a radiation passing through an object to have a radiation transmission image of the object stored on said recording material,
- (d) an image read-out section provided with a stimulating ray source for emitting a stimulating ray for scanning said recording material carrying said radiation image stored thereon, and a photoelectric read-out means for obtaining an electric image signal by reading out light emitted from said recording material scanned and stimulated with the stimulating ray,
- (e) a means for circulating said recording material on said supporting material with respect to said image read-out section for enabling reuse of said recording material by repeatedly moving said supporting material and said image read-out section with respect to each other, and
- (f) an erasing means for eliminating the radiation energy remaining on said recording material prior to image recording on said recording material after the radiation image is read out therefrom at said image read-out section.
