METHOD FOR CREATING MODEL FOR SURGERY SIMULATION, DEVICE FOR THE SAME, METHOD FOR SIMULATING SURGERY, AND DEVICE FOR THE SAME

摘要

PROBLEM TO BE SOLVED: To reduce loads in contact and bleeding determination processing of a large scale organ model constituted of a finite element model.SOLUTION: Finite element setting means forms models of finite elements obtained by dividing a simulation organ into the finite elements by computer graphics technology to obtain data on them. Search element setting means selects arbitrary one of the finite elements obtained in a finite element formation process. Meta data creation means sequentially creates pieces of new meta data by selecting the fixed number of sequentially adjacent element groups near a start point by using the one selected finite element as the start point to include all the finite elements of the simulation organ. The pieces of meta data are stored in meta data storage means. Contact and bleeding determination is more simply processed by using the newly created pieces of meta data than by all the finite elements of the simulation organ.
