Embodiment Construction
[0055] The present invention will be further described below in conjunction with the accompanying drawings.
[0056] refer to Figure 1 ~ Figure 3 , a tissue deformation method based on particle springs and hydrodynamics, the tissue deformation method comprising the steps of:
[0057] The first step is to establish a uniform triangular mesh for the tissue to be studied from the medical data;
[0058] The second step is to establish a physical model of a particle spring on the constructed tissue grid model;
[0059] The third step is to establish a fixed rigid body kernel and a generalized spring;
[0060] The fourth step is to fill the SPH model fluid in the constructed mass spring mesh model;
[0061] The fifth step is to set a rigid body occupying a certain space to transmit the load together with the fluid; the particle spring model simulates the skin deformation on the surface of the tissue, and the SPH model fluid and rigid body simulate the operating mechanism of the ...
