Abstract

Abstract The present invention writes the obtained two-dimensional image data of a body including a diseased portion in a computer or the like, and displays a three-dimensional image of the body including the diseased portion and the related data in the same monitor. The diseased portion data is then converted into a three-dimensional construction with use of a three-dimensional construction reconstructing section. The geometrical center of the three-dimensional constructed image is calculated by a geometrical center calculation section, and a plurality of linear lines or one linear line having the shortest distance directing from the geometrical center to the outside of the body is then calculated. The calculated line/lines is/are displayed to be overlapped on an image of the body including the diseased portion. In this manner, the present invention provides a stereotaxy operation route searching apparatus for showing a guideline of a low-invasive operation strategy to an operator, and the searching method.
