Claim Text:
1. A projection image generation apparatus comprising: a two-dimensional template storage that stores a two-dimensional template that two-dimensionally represents a schematic diagram of each path of a tubular structure composed of a plurality of three-dimensionally branching paths, and in which a corresponding relationship of anatomical positions between positions on the paths of the tubular structure and positions on paths of the two-dimensional template has been set in advance, the two dimensional template being that in which plural reference points are set in advance as branching positions on the path of the tubular structure and paths connecting the reference points are set in advance; one or more processors that operate as a projection image generator that generates a two-dimensional projection image by projecting voxel values of the tubular structure, where the voxel values are present along the paths of the three-dimensional structure extraction data, onto corresponding positions along the paths of the two-dimensional template, the projection image generator including
