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. <EOS>
