A medical image processing apparatus for analyzing properties of living body based on image data of the living body is provided. The medical image processing apparatus executes a predetermined image analysis processing on the image data of the living body, to obtain shape image data obtained by extracting a profile of the living body, and pattern image data obtained by extracting the pattern on the interior of the profile of the living body. A fractal dimension DA of the shape image data is calculated and a fractal dimension DB of the pattern image data is calculated based on the obtained shape image data and the pattern image data, and then, the index value CI is calculated which substantially excludes information of the shape image data and substantially includes information of the pattern of the pattern image data to judge the properties of the living body.
