1. A medical image processing device comprising: medical image information acquisition means configured to acquire plural sets of medical image information indicating a tomographic image of a femoral region in an object to be examined; evaluation region extraction means configured to extract an evaluation region from each of the plural sets of medical image information; evaluation region display means configured to display the evaluation region on a display device; and evaluation region comparative display means configured to specify a femur region and a muscle region from said evaluation region, execute a parallel transfer process, rotational transfer process and scaling process on at least one of the plural sets of medical image information to match the femur region, and display the medical image information that matched the femur region to compare each muscle region, wherein the evaluation region comparative display means sets a femur protrusion as a reference point, sets a reference line including the reference point and barycenter of the femur region, generates a graph with (i) an angle between a radius and the reference line on the horizontal axis and (ii) a distance on the radius from the reference point to the border of the muscle region on the vertical axis, and displays the graph on the display device.
