PURPOSE: To enable to clearly form an image of only an object directly existing on an axial line by enabling an X-ray receiving part to rotate on a circular track making its axial line as the center by synchronizing with the X-ray source. CONSTITUTION: An X-ray diagnosing equipment has an X-ray source 14 and an X-ray multiplier phototube 15 located oppositely to the X-ray source as an X-ray receiver. These are mounted on the both ends of C-shape curved body 16 bent to an arc shape. The C-shape curved body 16 is mounted movably and adjustably on a support member 8 in the direction of a double arrow markαalong its periphery. Namely, the C-shape curved body 16 can be rotated making its central axis line M as the center. The beam center ZS of X-ray flux in the X-ray diagnosing equipment is perpendicular to the central axis line M of the C-shape curved body 16. The C-shape curved body 16 is further mounted on the support member 8 so that the central axis line M of the C-shape curved body 16 and the beam center ZS are extended through the isocenter IZ. Namely, the beam center ZS is extended through the isocenter IZ against an arbitrary turning position of the C-shape curved body 16. |
