Abstract:
1. An X-ray diagnostic apparatus, comprising: a floor rotating arm, one end of the floor rotating arm being mounted on a floor surface so as to be rotatable around a substantially vertical first rotation axis: a stand mounted on the other end of the floor rotating arm so as to be rotatable around a substantially vertical second rotation axis; an arm holder mounted on the stand so as to be rotatable around a substantially horizontal third rotation axis; a substantially C-shaped, C-arm mounted on the arm holder so as to be slidable around a substantially horizontal fourth rotation axis, with an isocenter at which the fourth rotation axis intersects the third rotation axis being located on the first rotation axis when the C-arm is located immediately above the floor rotating arm; an X-ray generating unit mounted on one end of the C-arm; an X-ray detecting unit mounted on the other end of the C-arm; a catheterization table having a table top which is movable in a longitudinal direction, and in which the first rotation axis intersects a central line of the table top; and a control unit which controls rotation of the floor rotating arm around the first rotation axis and rotation of the stand around the second rotation axis upon interlocking therebetween in accordance with a specific user instruction such that the C-arm is located immediately above the floor rotating arm and the central line of the floor rotating arm inclines at a predetermined angle with respect to the central line of the table top.
