Abstract:
An X-ray diagnostic apparatus comprising:an X-ray tube configured to irradiate a subject with X-rays; a rectangular planar type X-ray detector formed by arraying a plurality of solid-state detection elements; a supporting mechanism configured to support said X-ray tube and said planar type X-ray detector in arbitrary postures with respect to the subject; a suspending mechanism configured to suspend said planar type X-ray detector from said supporting mechanism, said suspending mechanism including a rotating mechanism for rotating said planar type X-ray detector through an arbitrary angle about a central path of the X-rays, said rotating mechanism including an actuator configured to drive said planar type X-ray detector to rotate; a posture detector configured to detect postures of said X-ray tube and said planar type X-ray detector with respect to the subject; and a controller configured to control said actuator such that a corner of said planar type X-ray detector does not abut against the subject, thereby rotating said planar type X-ray detector through an angle corresponding to the detected posture.
