When an image representing an organ in which an excision region has been identified in such a manner that a blood vessel region in the organ is visually recognizable is generated from a three-dimensional image of the organ, an input specifying a depth of cutting is received, and a portion of a boundary surface within the specified depth of cutting along the boundary surface from an outer edge of the boundary surface toward an inside is determined as a cutting surface, and the boundary surface being between the excision region and a non-excision region in the organ. The image representing the organ in such a manner that only a partial blood vessel region, which is present in a neighborhood region of the cutting surface in the blood vessel region of the organ, is visually recognizable is generated from the three-dimensional image. |

1. A surgery assistance apparatus comprising:
an image generation unit that generates, from a three-dimensional image of an organ in which an excision region has been identified, an image representing the organ in such a manner that a blood vessel region in the organ is visually recognizable; a depth input receiving unit that receives an input specifying a depth of cutting; and a cutting surface setting unit that determines, as a cutting surface, a portion of a boundary surface within the specified depth of cutting along the boundary surface from an outer edge of the boundary surface toward an inside, and the boundary surface being between the excision region and a non-excision region, which is a region other than the excision region, in the organ, wherein the image generation unit generates, from the three-dimensional image, the image representing the organ in such a manner that only a partial blood vessel region, which is present in a neighborhood region of the cutting surface in the blood vessel region of the organ, is visually recognizable. |
