PROBLEM TO BE SOLVED: To support diagnosis of circulatory disturbance.SOLUTION: A medical image processing device according to an embodiment includes: an acquisition unit which acquires first density change information indicating the density change of a contrast agent in a first period, and second density change information indicating the density change of the contrast agent in a second period different from the first period by executing scan using an X-ray with respect to a subject to which the contrast agent is injected once； and an estimation unit which estimates the presence/absence of the circulatory disturbance of the subject on the basis of the input data including the first density change information and the second density change information.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2020,JPO&INPIT【課題】循環障害の診断をサポートすること。【解決手段】実施形態に係る医用画像処理装置は、造影剤が１度注入された被検体に対してＸ線を用いたスキャンを実行することで、第１の期間における前記造影剤の濃度変化を表す第１の濃度変化情報、及び、前記第１の期間とは異なる第２の期間における前記造影剤の濃度変化を表す第２の濃度変化情報を取得する取得部と、前記第１の濃度変化情報及び前記第２の濃度変化情報を含む入力データに基づいて、前記被検体の循環障害の有無を推定する推定部と、を備える。【選択図】図２
