Summary:To appropriately change a magnification rate of a display image dynamically in accordance with the advancement of a medical device without an operation by an operator.SOLUTION: An X-ray diagnostics device includes a first region-of-interest setting unit, an imaging unit, a second region-of-interest setting unit, a device detection unit, a magnification rate changing unit, and a display control unit. The first region-of-interest setting unit sets a first region of interest in a three-dimensional medical image on the subject. The imaging unit images the subject on the basis of the first region of interest, and acquires a plurality of X-ray images of the subject. The second region-of-interest setting unit sets a second region of interest on the basis of the arrangement of the imaging unit. The device detection unit detects a medical device inserted into the subject in the plurality of X-ray images. The magnification rate changing unit changes a magnification rate of a second X-ray image acquired later than a first X-ray image of the plurality of X-ray images on the basis of the position of the detected medical device. The display control unit causes a display unit to display a partial X-ray image in which the magnification rate after change is applied to a part corresponding to the second region of interest of the second X-ray image.SELECTED DRAWING: Figure 3 【課題】術者が操作することなく医用デバイスの進行に合わせて表示画像の拡大率をダイナミックに適切に変更すること。【解決手段】実施形態に係るＸ線診断装置は、第１関心領域設定部と、撮像部と、第２関心領域設定部と、デバイス検出部と、拡大率変更部と、表示制御部とを備える。第１関心領域設定部は、被検体に関する３次元医用画像において第１の関心領域を設定する。撮像部は、第１の関心領域に基づいて被検体を撮像して、被検体に対する複数のＸ線画像を取得する。第２関心領域設定部は、撮像部の配置に基づいて第２の関心領域を設定する。デバイス検出部は、複数のＸ線画像において、被検体に挿入された医用デバイスを検出する。拡大率変更部は、検出された医用デバイスの位置に基づいて、複数のＸ線画像のうち第１のＸ線画像より後に取得される第２のＸ線画像の拡大率を変更する。表示制御部は、第２のＸ線画像のうち第２の関心領域に対応する部分に変更後の拡大率を適用した部分Ｘ線画像を表示部に表示させる。【選択図】 図３
