1. A medical image processing apparatus, comprising:
processing circuitry configured to
acquire a geometry of a coronary artery depicted in data of images relating to a heart,
calculate a fractional flow reserve (FFR) value of the acquired coronary artery, based on the acquired geometry of the coronary artery, and
specify a target blood vessel from the coronary artery from which the FFR value was calculated; and
a display to display (1) the FFR value on a 2D image that depicts the target blood vessel, wherein a first axis of the 2D image represents a long axis of the specified target blood vessel and a second axis of the 2D image represents a short axis of the specified target blood vessel, (2) a first graph having a third axis representing FFR values of the specified target blood vessel and a fourth axis representing spatial locations for the FFR values, wherein the first and fourth axes are aligned to a scale of the 2D image, and (3) a second graph having a fifth axis representing index values that represent characteristics of a plaque and/or a calcification located in the target vessel, the index values being displayed at spatial locations corresponding to locations of the plaque and/or the calcification.
