PROBLEM TO BE SOLVED: To improve that the positional relationship between a surgeon and a console changes due to the movement of a top plate, which makes it difficult to operate the console. An X-ray diagnostic apparatus (100) includes a movable top plate (14) on which a subject is placed, an operation device provided on a side surface of the top plate, and an acquisition unit that acquires a position and an inclination angle of the top plate. 212, a calculation unit 213 for calculating the movement amount and the inclination angle of the operation device based on the movement amount of the position of the top plate and the change of the inclination angle of the top plate, and the calculated movement amount and inclination angle of the operation device. And a movement control unit 214 for controlling the movement mechanism to move or tilt the operating device. [Selection diagram] Figure 1【課題】天板の移動に伴い、術者とコンソールとの位置関係が変化して、コンソールの操作が困難になることを改善する。【解決手段】Ｘ線診断装置１００は、被検者を載置する移動可能な天板１４と、天板の側面に設けられた操作器と、天板の位置および傾斜角度を取得する取得部２１２と、天板の位置の移動量および天板の傾斜角度の変化に基づいて、操作器の移動量および傾斜角度を算出する算出部２１３と、算出された操作器の移動量および傾斜角度に基づいて、移動機構を制御して操作器を移動または傾斜させる移動制御部２１４と、を備える。【選択図】図１
