A triaxially controlled X-ray diagnostic apparatus comprises a support unit having a first arm, a second arm, and a third arm which are capable of rotation on three mutually orthogonal axes, an X-ray generator mounted on an end of the third arm for irradiating an object under examination with X rays, an image intensifier, mounted on the other end of the third arm so that it is opposed to the X-ray generator, for detecting X rays transmitted through the object to provide an optical image, a TV camera connected to the image intensifier for converting the optical image into a video signal to provide an X-ray image of the object, a display unit for displaying the X-ray image, and rotation correction means for making rotation correction on an X-ray image displayed on the display unit on the basis of angles of rotation of the first, second and third arms when they are rotated from their reference position.

X-ray diagnostic apparatus and X-ray diagnostic method

An X-ray diagnostic apparatus comprising X-ray generating unit for generating an X-ray to a patient, X-ray image detecting unit, provided to be apposite to the X-ray generating unit to sandwich the patient therebetween, for detecting an X-ray image, a holding apparatus for rotatably holding the X-ray generating unit and x-ray image detecting unit at a rotation axis, which is a line connecting the X-ray generating unit to the X-ray image detecting unit, and a supporting apparatus for rotatably supporting the holding apparatus at the same rotation axis.
