PROBLEM TO BE SOLVED: To provide an X-ray diagnostic apparatus capable of generating a pulse X-ray in a state in which an unnecessary exposure is reduced.SOLUTION: An X-ray diagnostic apparatus 1 according to an embodiment comprises: an X-ray tube 5 for generating an X-ray a plurality of rotation plates that are provided at an X-ray radiation window 53 in the X-ray tube 5, include a plurality of apertures, through which the X-ray passes, on a concentric circle having the same radius, and have the same rotation axis a plurality of rotation drive units for individually driving the rotation plates rotation and a control unit 27 that, in forming a pulse X-ray caused by intermittent interception of the X-ray using apertures on a rotated rotation plate, controls the rotation drive units in order to adjust a relative angular difference between two rotation plates of the rotation plates and rotation speed of the rotation plates.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】不要な被曝が低減された状態で、パルスX線を発生可能なX線診断装置の提供。【解決手段】本実施形態に係るX線診断装置1は、X線を発生するX線管5と、X線管5におけるX線放射窓に53設けられ、X線が通過する複数の開口部分を同一半径の同心円上に有し、同一の回転軸を有する複数の回転盤と、回転盤の回転をそれぞれ駆動する複数の回転駆動部と、回転された回転盤の開口部分によるX線の断続的な遮断に起因するパルスX線の形成において、回転盤のうちの2つの回転盤の相対的な角度差と回転盤の回転速度とを調節するために、回転駆動部を制御する制御部27と、を具備する。【選択図】図1
