Abstract:
1. A computer-readable, non-transitory storage medium storing a program for causing a computer to execute a shape data generation process, the shape data generation process comprising: accepting designation of a start point in a reference shape identified from data of predefined vertices and designation of a target point corresponding to the start point in a first shape that is identified from image data and is a target shape of transformation, wherein an object relating to the reference shape and the first shape is a heart, and a portion to which the start point and the target point are designated is at least one of an apex, a bottom section of a right ventricle fluid surface, a myocardial boundary, a pulmonary vein, and an inferior vena cava of the heart; generating a second shape, by first transforming the reference shape so as to place the start point on the target point; identifying, from among a plurality of vertices of the second shape, one or plural first vertices satisfying a predetermined condition including a first condition that a normal line of a vertex to be processed includes a boundary point on the first shape, a second condition that a distance between the vertex to be processed and any other vertex of the one or plural first vertices is a predetermined first distance or more, and a third condition that the vertex to be processed does not correspond to the start point; second transforming the second shape so as to move each of the one or plural first vertices to a point that is located on the normal line, wherein the point is located from the first vertex at a second distance calculated by multiplying a distance between the first vertex and the boundary point by a ratio of a number of times of transformation already performed to a total number of times of transformation, and the second transforming is performed so as not to move the start point; and storing data concerning the plurality of vertices of the transformed second shape after the identifying and the second transforming are executed the total number of times of transformation.
