Summary:To improve accuracy of risk evaluation.SOLUTION: A medical image processing apparatus according to an embodiment comprises: an acquisition unit; a setting unit; and a calculation unit. The acquisition unit acquires a first parameter about the force in a coronary artery of a subject and a second parameter about at least one of the shape, characteristic and fluid resistance in the coronary artery. The setting unit sets a weighting factor corresponding to the anatomical position of the coronary artery to at least one of the first parameter and the second parameter. The calculation unit calculates an index about the risk of the subject on the basis of the first parameter, the second parameter and the weighting factor.SELECTED DRAWING: Figure 1 【課題】リスク評価の精度を向上させること。【解決手段】実施形態に係る医用画像処理装置は、取得部と、設定部と、算出部とを備える。取得部は、被検体の冠動脈における力に関する第１のパラメータと、冠動脈における形状、性状および流体抵抗のうち少なくとも１つに関する第２のパラメータとを取得する。設定部は、第１のパラメータ及び第２のパラメータのうち少なくとも一方に対して、冠動脈の解剖学的位置に対応付けた重み付け係数を設定する。算出部は、第１のパラメータと第２のパラメータと重み付け係数とに基づいて、被検体のリスクに関する指標を算出する。【選択図】図１
