[0074] The technical solutions of the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings.
[0075] The present invention provides a method of using implicit surface algorithm to simulate soft tissue surgery path planning. Here, liver tissue is taken as an example of soft tissue. The steps of the method are as follows:
[0076] S1: Obtain medical imaging data of the liver of a specific case;
[0077] S2: Establish a three-dimensional geometric model, specifically, use a visualization algorithm to generate a mesh model of the liver tissue structure, or use the volume rendering data of the medical imaging software as the volume element model;
[0078] For example, algorithms such as Marching Cubes are often used for 3D model reconstruction of medical image data. Many open source tools such as VTK and commercial software that comes with clinical imaging equipment have these functions;
[0079] The volume renderin...
