  • Patent number: 10226199
    Abstract: An information processing apparatus includes an acquisition unit, a specification unit, a determination unit, a generation unit, and a display control unit. The acquisition unit acquires a three-dimensional image containing at least a tubular structure. The specification unit specifies a first point inside the tubular structure and specifies a lesion outside the tubular structure in the three-dimensional image. The determination unit determines whether a blood vessel is present in a region between the first point and the lesion based on signal values of voxels of the three-dimensional image in the region between the first point and the lesion. The generation unit generates a two-dimensional image of the tubular structure viewed from the first point based on the three-dimensional image. The display control unit displays information indicating a region of the lesion on the two-dimensional image to be distinguishable in determining whether a blood vessel is present in the region.
