1. A medical image processing apparatus, comprising:
processing circuitry configured to
obtain medical image data related to a coronary artery of a subject;
derive a value of a blood flow parameter indicating hemodynamics of the coronary artery based on the medical image data;
display information indicating a change in the value of the blood flow parameter along the coronary artery, by using a graph of which a horizontal axis corresponds to a distance direction along the coronary artery and which represents values of the blood flow parameter;
display supplementary information indicating a structure of the coronary artery together with the graph;
display, in the graph, a first marker, a second marker, and a third marker, wherein the first marker is displayed in a position having a largest stenosis ratio of the coronary artery, the second marker is displayed in a position away from the position of the first marker toward an upstream side of the coronary artery, and the third marker is displayed in a position away from the position of the first marker toward a downstream side of the coronary artery; and
display a value of a cross-sectional area of the coronary artery in the position in which the first marker is displayed, a value of a cross-sectional area of the coronary artery in the position in which the second marker is displayed, a value of a cross-sectional area of the coronary artery in the position in which the third marker is displayed, and a delta value of the blood flow parameter at a position between the position of the second marker and the position of the third marker, so that the values of the cross-sectional areas and the delta value are displayed side by side in the distance direction.
