Abstract

A medical image processing device is characterized in comprising an edge extracting unit for extracting a two-dimensional image of a biomedical tissue input from a medical image picking-up device; a three-dimensional model estimating unit for estimating a three-dimensional image of the biomedical tissue; a local region setting unit for setting a local region where a pixel of interest is treated as the center in the two-dimensional image; a judging unit for judging whether or not the local region is divided by at least a part of the edge extracted in the extracting unit; a shape characteristiccalculating unit for calculating a shape characteristic amount of the pixel of interest while using three-dimensional data of regions that are not divided by the edge in the edge extracting unit out of the local region based on a judging result of the judging unit and that correspond to a region where the pixel of interest exists; and a projecting shape detecting unit for detecting a projecting shape based on a calculation result of the shape characteristic amount calculating unit.

Description

technical field

[0001] The present invention relates to a medical image processing device and a medical image processing method, and more particularly to a medical image processing device and a medical image processing method for estimating a three-dimensional model of a living tissue from a two-dimensional image of the living tissue. Background technique

[0002] Conventionally, in the medical field, observation using imaging equipment such as X-ray diagnostic equipment, CT, MRI, ultrasonic observation equipment, and endoscope equipment has been widely performed. The endoscope device in this kind of image pickup equipment has the following functions and structures, for example: it has an insertion portion that can be inserted into a body cavity, and the objective optical system configured at the front end of the insertion portion is photographed by an imaging unit such as a solid-state imaging device. The captured image inside the body cavity is output as an imaging signal,...
