<p>PURPOSE: To ensure a structure and an operation by providing an optical detecting member which moves in synchronization with the movement of an X-ray fan beam, and which has a plurality of charge transfer devices which are electrically connected together in rows or columns, and a digital process means so that signals are synchronously shifted in a direction opposite to the moving direction of the photo-detecting member. CONSTITUTION: A movable scanning member 18 is operated in synchronization with a composite X-ray converting and photo-detecting member 28. An output signal therefrom passes through a digital processing means 32, and is recorded on an electronic recording means 34 such as a magnetic tape. A movable rod-shape scintillator body 38 forms a composite member 28 when it is simultaneously coupled with movable bidirectional charge transfer arrays 42, and converts it into an optical image and then into an electrical signal. Since charge transfer devices 44 are connected electrically with one another, they are aligned with rows 46 or columns 48 as a whole so as to be constituted into a module shape in order to serve as optical points of pixels. Charge transfer devices 44 in an example in the optical detecting member 42 are arranged in zigzagged vertical rows so as to establish a continuous pixel display.</p> |
