PURPOSE:To improve an SN ratio, by arranging plural stripe-like radiation detecting elements in parallel, detecting and processing numbers of signals from the same element while shifting the detecting elements in position from a radiation image, and reconstituting an image and also reducing divisions of a screen. CONSTITUTION:An image of an object is formed on the screen through a pinhole plate. A radiation detector 4 consisting of the stripe-like radiation detecting elements 401, 402-414 arranged in parallel is provided in the center of the screen. The detector 4 is rotated at intervals of 15 deg. by an output signal from a controller 6 through the gear engagement between a pulse motor 6 and the detector 4. The controller 6 sends a read indication signal to a serializing device 7 and a write address signal to a storage device 9, and the output signal of each element regarding the ratiation image is stored in a corresponding address of the storage device through an AD converter 8. A computing element 10 processes and stores the signal data in a storage device 12, and divisions of the screen on a monitor 13 are reduced through a DA converter 12 to display a picture with an excellent SN ratio. |
