Embodiment Construction
[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0047] The present invention provides a method for simulating soft tissue deformation and path cutting, such as figure 1 shown, including the following steps:
[0048] Step 1: Use the finite element model to simulate the deformation of the soft tissue to be simulated, and apply the model reduction method combining intrinsic orthogonal decomposition and Galerkin projection to achieve model reduction during the deformation simulation process.
[0049] According to the medical image data, the finite element model based on the model reduction method is used to construct the deformation model of human organs, and the solution results of a set of finite element full-order models are taken as samples, and on this basis, the eigenorthogonal decomposition and Galio The model reduction method combined with golden projection reduces the full-order model to a reduced-or...
