Radiation image recording and read-out system

Claim 1

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.

Claim 6

A system as defined in any of claims 1 to 4 wherein said recording material is a stimulable phosphor layer formed on said supporting material.

Claim 7

A system as defined in any of claims 1 to 4 wherein said recording material is a stimulable phosphor sheet releasably secured to said supporting material.

Claim 8

A system as defined in any of claims 1 to 4 wherein said supporting material is capable of being circulated between said image recording section and said image read-out section.
