X-RAY DIAGNOSTIC INSTRUMENT

PROBLEM TO BE SOLVED: To provide an X-ray diagnostic instrument for relieving burden on an operator and a patient as much as possible, and also easily securing the visual field of an image required for the advance of an examination. SOLUTION: This instrument includes a mechanism for moving only a detector 3 in parallel along the detection surface. The detector 3 is moved in parallel by operating an exclusive operation lever 14. Besides, a system is constituted to automatically adjust the direction of an X-ray tube 2 in response to the movement of the detector 3, and also adjust the aperture position and opening degree of an aperture 2a. A system is also constituted to automatically correct a distortion of an image to be displayed on a monitor, and also adjust the center position of a reference image or a mask image in the case of load mapping to meet that of the image to be displayed on the monitor in response to the movement of the detector 3.
