Cardiac function display apparatus and program therefor
First Claim
1. A cardiac function display apparatus, comprising:
- a functional image generation unit for generating a functional image representing a function of a heart in each position using first voxel data of a three-dimensional medical image obtained by photographing a subject;
a morphological image generation unit for generating, using a portion of second voxel data of a three-dimensional medical image obtained by photographing the subject, which are identical to or different from the first voxel data, corresponding to an area which includes a blood vessel along an outer myocardial wall of the heart, a morphological image depicting morphology of the blood vessel; and
a superimpose display unit for displaying the functional image and the morphological image in a superimposing manner such that each position of the heart in the functional image corresponds to each position of the heart in the morphological image, wherein;
the functional image is an image in which images representing functions of the heart on a plurality of slice planes cut in a direction traversing a major axis extending from a cardiac base toward a cardiac apex of the heart are arranged concentrically, andan image representing a function of the heart on a slice plane near the cardiac base of the heart is disposed near the center of the concentrically arranged images and an image representing a function of the heart on a slice plane closer to the cardiac apex of the heart is disposed in a position farther away from the center.

Abstract
Using first voxel data of a three-dimensional medical image obtained by photographing a subject, a functional image representing a function of a heart in at least one position is generated, and using a portion of second voxel data of a three-dimensional medical image obtained by photographing the subject corresponding to an area which includes a blood vessel along an outer myocardial wall of the heart, a morphological image depicting morphology of the blood vessel is generated. Then, the functional image and the morphological image are displayed in a superimposing manner such that at least one position of the heart in the functional image corresponds to at least one position of the heart in the morphological image.
