Claim One:
1. A medical image processing apparatus comprising: an image storage that stores a two-dimensional image of an image of body tissues inside a body cavity inputted from a medical image pickup apparatus; a three-dimensional model estimating section that estimates a three-dimensional model of body tissues based on the two-dimensional image of the image of the body tissues inside the body cavity inputted from the medical image pickup apparatus; a voxel detecting section that detects one voxel existing on a nearest side in a view direction of the medical image pickup apparatus among voxels included in the three-dimensional model; a raised shape detecting section that acquires one curved surface including the one voxel to detect a position with gradient variation on the one curved surface and to determine whether or not body tissues with a locally raised shape exist in the position in the three-dimensional model; and the raised shape detecting section traces the one curved surface along a plurality of trace lines set parallel to a predetermined axial direction, and then determines that the body tissues with a locally raised shape exist in one position when detecting that the number of trace lines with intensity gradient variation in the one position in the predetermined axial direction among the plurality of trace lines is equal to or larger than one and equal to or smaller than a predetermined threshold value.
