Patent ID: 7261464

Claim:
An X-ray diagnostic apparatus comprising: a floor rotating arm installed at one end on a floor surface so as to be rotatable around a first rotation axis; a C-arm mounted on the other end of the floor rotating arm so as to be rotatable around a second rotation axis; an X-ray tube mounted on one end of the C-arm; an X-ray detector mounted on the other end of the C-arm; and a bed including a table top provided to be movable along a longitudinal axis, the bed being placed such that the longitudinal axis is spaced apart from the first rotation axis by a predetermined distance, wherein a distance between the second rotation axis and an imaging axis is substantially equal to a distance between the first rotation axis and the second rotation axis, and the imaging axis is an axis which connects an X-ray focal point of the X-ray tube to a center of the X-ray detector, wherein a distance between the longitudinal axis and the first rotation axis is equal to a distance between the first rotation axis and the second rotation axis.
