Document Type and Number:
Japanese Patent JP5347003
Kind Code:
B2
Abstract:
A medical image processing device for extracting an endocardium of a left ventricle from 3D image data representing the left ventricle is provided. The device includes: a blood region extracting unit to extract a blood region in the left ventricle from the image data; a convex and concave points identifying unit to find a convex hull from sample points on a contour of the extracted blood region and identify convex points forming the convex hull and concave points, which are sample points other than the convex points; and an endocardium determining unit to deform the contour of the blood region by moving at least a part of the concave points outward from the blood region by an amount determined based on a positional relationship among each concave point and the convex points located around the concave point and determine a deformed contour of the blood region to be the endocardium.
