PROBLEM TO BE SOLVED: To generate a three-dimensional image and a two-dimensional image whose angle of fluoroscoping is variable with a single device by providing a means to set optionally the angle of irradiation of X-rays in the axial direction of the body of a subject in the first supporting member and providing a means to arrange an image receiving means in opposition to the set angle of irradiation in the second supporting member. SOLUTION: An X-ray tube 2 is supported movably on a curved surface around an isocenter Z formed in an arm 1 supporting the X-ray tube 2 and fixed to a rotating plate 7 along a curved guide 3 and similarly an arm 4 fixed to the rotating plate 7 is disposed in a position opposite to the X-ray tube 2, interposed by a subject. An X-ray image receiving means 5 that detects X-rays transmitting the subject is supported movably in a curved surface 6 around the isocenter Z along the curved guide 6. The rotating plate 7 is supported on a supporting frame 8 supporting the rotating plate 7 through at least a pair of bearings 11 and rotated through a belt 10 or the like by the driving of a driving portion 9. |
