ABSTRACT:
A radiation image recording and read-out apparatus comprises a belt feed device for positioning and moving a flexible, endless stimulable phosphor belt in its longitudinal direction, so that two desired portions of the stimulable phosphor belt, which have support sides that face each other, may be positioned for exposure to radiation in such a way that the support sides are in close, face-to-face contact with each other or are approximately parallel to and slightly spaced apart from each other. In an image recording section, radiation carrying image information is irradiated onto two portions of the stimulable phosphor belt, which have support sides that face each other and which have been positioned so as to be exposed to the radiation, and radiation images are thereby stored on the two portions. In a single image read-out section, the radiation images are read out from the two portions. The two portions are then erased in an erasing section. In an operating section, two image signals detected from the two portions in the image read-out section are added together or subtracted from each other.
