Abstract: According to one embodiment, an X-ray diagnostic apparatus includes an X-ray tube, a driver, a supporter, and processing circuitry. The X-ray tube including a rotating anode. The driver rotates the rotating anode. The supporter supports the X-ray tube in an inclinable manner. The processing circuitry acquires information indicating an attitude of the supporter and controls the driver based on information indicating the acquired attitude.

Abstract: An X-ray diagnostic apparatus according to an embodiment includes: an X-ray tube including a target configured to generate X-rays in response to emission of electrons thereto, a plurality of filaments configured to emit electrons into substantially the same position on the target, and a grid used in common among the plurality of filaments; intermediate potential setting circuitry configured to set intermediate potential in a position between the plurality of filaments and the target by using the grid; and filament potential controlling circuitry configured to change one or more filaments selected from among the plurality of filaments to emit the electrons to the target, by controlling potential levels of the plurality of filaments with respect to the intermediate potential for each filament, in conjunction with switching of X-ray tube voltage.

Abstract: An operation device comprises a detector configured to detect an operation on a virtual switch by an operator to operate an X-ray irradiation in an X-ray diagnosis apparatus, wherein the virtual switch is virtually set at a position settled relatively with respect to the operator and output circuitry configured to output a detection result of the operation detected by the detector to the X-ray diagnosis apparatus to be operated. This device eliminates the need for looking away from a display monitor every time the operator operates the X-ray diagnosis apparatus.
