Paper Abstract

In this paper, we have proposed the construction method of the geometry model of the brain tumor by the three-dimensional(3-D) Active Sphere. 3-D Active Sphere, which is a kind of the energy-minimizing method, is able to extract the three-dimensional geometry model directly from the volume data sequences composed of the MRI slice images. The method enables us more accurate and direct extraction of a three-dimensional geometry model than the previous energy-minimizing method, because both the boundary and the interior information are used for the modification of the object in our method.
