[Problem] To project an image onto a two-dimensional plane so that an anatomical position of a three-dimensionally branching tubular structure is recognizable, and to display the image. [Solution Means] A structure extraction means (62) obtains three-dimensional structure extraction data by extracting a tubular structure from volume data obtained by imaging a predetermined subject. A relating means (64) relates positions on paths of a two-dimensional template (68) representing a schematic diagram of a three-dimensionally branching tubular structure obtained by imaging a predetermined subject and positions on paths of the three-dimensional structure extraction data to each other. A projection image generation means (65) generates a two-dimensional projection image by projecting voxel values of the tubular structure that is present on the paths of the three-dimensional structure extraction data onto corresponding positions on the paths of the two-dimensional template (68). |
