Abstract

for the medicla analysis of the three-dimensional structure such as the mandible, it is necessary to reconstruct the structure into the finite number of analyzable elements. The information of the three-dimensional structure can be obtained from the cross-sections of the magnetic resonance image (MRI). A region corresponding to the structure is extracted from the inner part of the cross-section. By the triangulation of the sampled cross-section image, two-dimensional finite elements are generated. There-dimensional finite elements are constructed by matching the two-dimensional finite elements each other in space. In this paper s construction method of the optimal three-dimensional finite elements has been suggested, which uses the adjacent information abstracted from the triangulated two-dimensional finite elements. The elements are classified into the identical property sets by using the adjacent information of the triangulated two-dimensional elements. After applying the multistep matching algorithm to the classified two-dimensional finite elements, the optimal three-dimensional finite elements can be constructed. By analyzing the constructed finite elements, it is possible to get much more useful medical information about the three-dimensional structure of mandible.
