MEDICAL IMAGE PROCESSING APPARATUS AND METHOD THEREOF
First Claim
1. A medical image processing apparatus comprising:
- an acquiring unit configured to acquire volume data of a heart;
a coordinate system detecting unit configured to detect a three-dimensional left ventricle coordinate system composed of three axes including at least a left ventricle long axis of the heart from the volume data;
a boundary detecting unit configured to use a boundary model expressed in the left ventricle coordinate system to detect a left ventricle boundary from the volume data by deforming the boundary model so that an error between a boundary pattern obtained by applying the boundary model to the volume data and a predetermined boundary pattern model becomes small; and
a display unit configured to display the detected left ventricle boundary on a cross-sectional image together with the cross-sectional image orthogonal to at least one axis of the three axes of the left ventricle coordinate system.

Abstract
[Object] The invention is intended to provide a medical image processing apparatus in which improvement of accuracy of boundary detection of a heart is achieved.
[Solving Means] A medical image processing apparatus acquires volume data of a heat, detects a three-dimensional left ventricle coordinate system composed of three axes including at least a left ventricle long axis of the heart from the volume data; uses a boundary model expressed in the left ventricle coordinate system and detects a left ventricle boundary from the volume data, and displays a cross-sectional image orthogonal to at least one axis of the three axes of the left ventricle coordinate system together with the detected left ventricle boundary on the cross-sectional image.
