<p>PURPOSE:To raise detection efficiency of scattered radiation with a small detector and improve the SN ratio of an image. CONSTITUTION:The title system has a radiation generation and scanning means 5 to scan radiation on to a detected body which is provided under a belt conveyer 7 to convey the detected body, a scattered ray detector 10 to detect the scattered ray generated in the detected body which is provided in the middle of upper and lower belts of the belt conveyer 7 and has a passage 11 to pass the radiation emitted from the radiation generation and scanning means 5, and an imaging means to image the output from the scattered ray detector 10.</p> |
