发明名称 Apparatus for recording a radiation image of an object on a stimulable phosphor sheet to facilitate later reconstruction of an arbitrary tomographic image of the object
摘要 A radiation image recording apparatus comprises a radiation source for emitting a radiation to an object, a device for moving the radiation source to change the irradiation angle, a sheet changer for feeding a stimulable phosphor sheet to an image recording position exposed to the radiation passing through the object to have a radiation image of the object stored on the stimulable phosphor sheet and then receiving a drive signal to remove the stimulable phosphor sheet from the image recording position and feed a next stimulable phosphor sheet thereto, and a device for moving the sheet changer so that the stimulable phosphor sheet at the image recording position and the radiation source satisfy the linear rule and the geometric rule with respect to a point within the object or in the vicinity thereof. A controller controls operations of the devices for moving the sheet changer and the radiation source, intermittently activates the radiation source to emit the radiation at different irradiation angles, and sends the drive signal to the sheet changer after the radiation source is activated.
