Abstract
According to one embodiment, a medical image processing apparatus includes first specifier, second specifier, determiner and display controller. First specifier collates an ischemic region calculated from a blood vessel visualized into a three-dimensional image in a plurality of phases with a dominating region of the blood vessel, and specifies a culprit vessel in the ischemic region. Second specifier specifies a culprit stenosis in the culprit vessel based on a pressure index calculated from the blood vessel. Determiner determines a connection position to connect a bypass vessel that makes a detour around the culprit stenosis. Display controller displays the determined connection position on a display.

A computer-implemented coronary artery analyzing method, comprising:
- acquiring a blood flow index corresponding to a pressure ratio between two points in a coronary artery, the blood flow index being obtained based on the coronary artery in three-dimensional volume data;
- specifying an inappropriate bypass portion of the coronary artery, where forming a bypass connection is inappropriate, based on a three-dimensional image and the blood flow index, the three-dimensional image being rendered from the three-dimensional volume data;
- writing, into a memory, a position distribution of the inappropriate bypass portion in a three-dimensional space, the position distribution being obtained based on the three-dimensional image and the blood flow index;
- and
- causing a display to display a location of the specified inappropriate bypass portion together with a marker superimposed on the three-dimensional image based on the position distribution written into the memory, the specified inappropriate bypass portion being displayed in a distinguishable manner.
A coronary artery analyzing system, comprising:
- a memory;
- and
- processing circuitry configured to
- acquire a blood flow index corresponding to a pressure ratio between two points in a coronary artery, the blood flow index being obtained based on the coronary artery in three-dimensional volume data,
- specify an inappropriate bypass portion of the coronary artery, where forming a bypass connection is inappropriate, based on a three-dimensional image and the blood flow index, the three-dimensional image being rendered from the three-dimensional volume data,
- write, into the memory, a position distribution of the inappropriate bypass portion in a three-dimensional space, the position distribution being obtained based on the three-dimensional image and the blood flow index, and
- cause a display to display a location of the specified inappropriate bypass portion together with a marker superimposed on the three-dimensional image based on the position distribution written into the memory, the specified inappropriate bypass portion being displayed in a distinguishable manner.
A non-transitory computer-readable storage medium having stored thereon instructions that, when executed, cause a processor to perform:
- acquiring a blood flow index corresponding to a pressure ratio between two points in a coronary artery, the blood flow index being obtained based on the coronary artery in three-dimensional volume data;
- specifying an inappropriate bypass portion of the coronary artery, where forming a bypass connection is inappropriate, based on a three-dimensional image and the blood flow index, the three-dimensional image being rendered from the three-dimensional volume data;
- writing, into a memory, a position distribution of the inappropriate bypass portion in a three-dimensional space, the position distribution being obtained based on the three-dimensional image and the blood flow index;
- and
- causing a display to display a location of the specified inappropriate bypass portion together with a marker superimposed on the three-dimensional image based on the position distribution written into the memory, the specified inappropriate bypass portion being displayed in a distinguishable manner.
