PURPOSE:To display a radioscopic image of a subject to be examined whereby the three-dimensional structure of the subject to be examined can be grasped with ease. CONSTITUTION:A conical X-ray beam radiated from an X-ray tube 1 is converted by a fixed colimeter 14 into a sector X-ray beam, which is in turn converted into a flying pencil X-ray beam for scanning using as scanning faces two parallel circular planes having a radiation source as their apex. X-rays scattered from a subject 7 to be examined which is moved by a conveyor 8 are detected by a scattered X-ray detector 19 as to the whole scanning face by an X-ray which scans the first scanning face 301 and by a pencile X-ray beam which scans the second scanning face 302. A scattered X-ray image of the subject 7 to be examined which is obtained from the pencile X-ray beam by which the first scanning face 301 is scanned is made to correspond to the left-eye image and a scattered X-ray image of the subject 7 to be examined which is obtained from the pencile X-ray beam by which the second scanning face 302 is scanned is made to correspond to the right-eye image, thereby providing three-dimensional display. |
