A cardiac function display apparatus, comprising a functional image generation means for generating a functional image representing a function of a heart in at least one position using first voxel data of a three-dimensional medical image obtained by photographing a subject; a morphological image generation means 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, including a width of the blood vessel, and morphology of a tissue along the outer myocardial wall other than the blood vessel; and a superimpose display means for displaying the functional image and the morphological image 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, characterized in that 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, and the functional image is an image in which an image representing a function of 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 a slice plane closer to the cardiac apex of the heart is disposed in a position farther away from the center. a functional image generation means for generating a functional image representing a function of a heart in at least one position using first voxel data of a three-dimensional medical image obtained by photographing a subject; a morphological image generation means 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, including a width of the blood vessel, and morphology of a tissue along the outer myocardial wall other than the blood vessel; and a superimpose display means for displaying the functional image and the morphological image 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, characterized in that 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, and the functional image is an image in which an image representing a function of 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 a slice plane closer to the cardiac apex of the heart is disposed in a position farther away from the center.
