Abstract

Recently, there are growing needs for accurate and interactive surgical training systems with realistic sensation. However, it takes large computation time to achieve such simulations. Our goal is to construct interactive operation training systems for doctors to practice the ablation operation. In this paper, we propose an efficient deformation and ablation simulation using online re-mesh and edge-based non-linear finite element models. In the simulation, meshes of elastic objects are refined and cut adaptively based on Mises stress. The Mises stress is computed efficiently because of the rectangular tetrahedral mesh feature, each having 3 orthogonal axes or planes. In experiment, by evaluation of accuracy of deformation and Mises stress and computation time, effectiveness of our approach was confirmed.
