Abstract
The three-dimensional image processing apparatus includes a surface data generation unit that extracts a display target from a three-dimensional image and generates surface data indicating a surface of the display target, a color information acquisition unit that performs a volume rendering process for the three-dimensional image of a specific section including a vertex of the surface data in a direction from the outside to the inside of a surface forming the surface data to acquire color information and assigns a color to the surface of the surface data on the basis of the color information, and a display control unit that displays the surface data having the surface, to which the color has been assigned, on a display unit.
