To improve image quality.SOLUTION: A medical image diagnostic apparatus according to the embodiment includes a bed, a first medical image diagnostic unit, a second medical image diagnostic unit, and a control unit. The bed supports a top plate, on which a subject is placed, so as to be movable in a shorter direction of the top plate. The first medical image diagnostic unit includes a first opening and is adjacent to the bed. The second medical image diagnostic unit includes a second opening forming perforation with the first opening and is disposed so as to be adjacent to the first medical image diagnostic unit. On the basis of a positional deviation amount between the first opening and the second opening, the control unit controls the top plate's position in the shorter direction.SELECTED DRAWING: Figure 1【課題】画質を向上させる。【解決手段】本実施形態に係る医用画像診断装置は、寝台と、第１の医用画像診断部と、第２の医用画像診断部と、制御部とを含む。寝台は、被検体が載置される天板を当該天板の短手方向に対して移動可能に支持する。第１の医用画像診断部は、第１の開口を有し、前記寝台に隣接する。第２の医用画像診断部は、前記第１の開口と貫通する第２の開口を有し、前記第１の医用画像診断部と隣接して配置される。制御部は、前記第１の開口と前記第２の開口との位置ずれ量に基づいて、前記天板の前記短手方向に関する位置を制御する。【選択図】図１
