To perform appropriate imaging of the heart.SOLUTION: A medical image diagnostic apparatus in an embodiment includes a specification part and a processing part. The specification part acquires heart sound information and electrocardiographic information from an analyte, and specifies a time phase of imaging or of reorganization from the heart sound information and the electrocardiographic information. The processing part performs imaging of the analyte based on the time phase of the imaging, or performs reorganization of the analyte based on the time phase of the reorganization.SELECTED DRAWING: Figure 1【課題】心臓の適切な撮影を可能にすること。【解決手段】実施形態に係る医用画像診断装置は、特定部と、処理部とを備える。特定部は、被検体から心音情報及び心電情報を取得し、前記心音情報及び前記心電情報から撮影又は再構成の時相を特定する。処理部は、前記撮影の時相に基づいて前記被検体の撮影を行い、又は、前記再構成の時相に基づいて前記被検体の再構成を行う。【選択図】図１
