Three-dimensional surgery simulation system

DETAILED DESCRIPTION Therefore, the object of the present invention is to provide a three-dimensional surgery simulation system that facilitates simulation of various surgical procedures in a three-dimensional environment with relatively high accuracy and at a relatively low cost.
According to the present invention, there is provided a three-dimensional surgery simulation system for generating a three-dimensional surgery simulation result of an anatomical part undergoing a simulated surgical procedure.
The system comprises: a display unit; a three-dimensional visual imaging unit adapted to be worn by an operator for viewing three-dimensional images on the display unit; a storage unit for storing a plurality of voxelized three-dimensional model image data sets, including at least one of a pre-operation anatomical data set, a surgical instrument data set, an implant data set, and a simulation result data set; an input unit adapted to be operated by the operator for controlling progress of the simulated surgical procedure; and a computing unit coupled to the display unit, the storage unit and the input unit, the computing unit computing the simulation result data in accordance with the voxelized three-dimensional model image data sets and under the control of the input unit, and controlling the display unit to permit viewing of the surgery simulation result in three-dimensional form thereon by the operator when the operator wears the visual imaging unit.
When the computing unit detects the surgery simulation result to have a first boundary face with a discontinuous edge that is common to at least a second boundary face, the computing unit processes the first and second boundary faces as a common closed surface, and assigns two voxels sharing the common closed surface as seeds for seed-and-flood algorithm computations during surface voxelization in the generation of the simulation result data.
