Radiation image recording and read-out apparatus.

摘要

A radiation image recording and read-out apparatus comprises a radiation source (10) for irradiating a radiation toward an object (11), a recording and read-out unit (20) for recording a radiation image of the object on a stimulable phosphor sheet at an image recording position and reading the radiation image therefrom, and a movement system for moving the recording and read-out unit and the radiation source so that the stimulable phosphor sheet at the image recording position approximately satisfies the linear rule and the geometric rule with respect to the radiation source around an arbitrary tomographic layer. The recording and read-out unit is provided with a case having a size nearly equal to a single image recording area on the stimulable phosphor sheet, an image recording section, an image read-out section provided in the case for reading the radiation image from the stimulable phosphor sheet by exposure to stimulating rays, and an erasing section provided in the case.
