Fig. 4

Heterogeneous structure of deformable model. The purple line is the parenchyma and the red line is the lesion. The boundary vertices are splitted into two vertices which respectively represent parenchyma and lesion. The imaginary line represents that there are now springs and the boundary vertices not involved in the TLED FEM modeling, which are represented by its neighboring vertices using MLS method. The green points represent the new positions of vertices on the hexahedral model in the next time step
