METHOD OF GENERATING MODEL FOR OPERATING SIMULATION, OPERATING SIMULATION METHOD AND OPERATING SIMULATOR

摘要

PROBLEM TO BE SOLVED: To provide a method of generating a model for operating simulation according to the operating state from a medical image, an operating simulation method and an operating simulator.

SOLUTION: This method of generating a model for operating simulation includes: a first process of acquiring geometric information from the medical image and organizing necessary volume data of an organ; a second process of meshing the organ of the generated volume data after the first process; a third process of forming two or more layers of simulation membranes covering the predetermined organ subjected to meshing in the second process; and a fourth process of extending a virtual line from each node of the surface of the predetermined organ subjected to meshing in the second process in a predetermined direction, forming a membrane surface node by an intersection between the virtual line and the simulation membrane formed in the third process, disposing a virtual inter-membrane spring connecting between each node of the surface of the predetermined organ and the membrane surface node and between the membrane surface nodes in each virtual line, and disposing a surface direction spring to form a mesh between the membrane surface nodes in each simulation membrane surface.
