PROBLEM TO BE SOLVED: To provide a medical image diagnostic device capable of setting an imaging condition in which an exposure dose is reduced while maintaining image quality.SOLUTION: A medical image diagnostic device includes: a shape specification unit for extracting an anatomical feature point from a medical image acquired by detecting an X-ray that has transmitted a subject in scanning before main scanning, and specifying a shape of an anatomical region of the subject based on the anatomical feature point and an imaging condition setting unit for setting a tilt angle according to the shape of the anatomical region in an imaging condition of the main scanning including a tilt.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】画質を維持しつつ、被曝線量を低減した撮像条件を設定可能な医用画像診断装置を提供する。【解決手段】一実施形態に係る医用画像診断装置は、本スキャン前のスキャンにおいて被検体を透過したX線を検出することで取得された医用画像から解剖学的特徴点を抽出し、前記解剖学的特徴点に基づいて前記被検体の解剖学的部位の形状を特定する形状特定部と、チルトを含む前記本スキャンの撮像条件において前記解剖学的部位の形状に応じてチルト角を設定する撮像条件設定部とを備える。【選択図】 図3
