We introduce a non-linear extension of the tensor-mass method for real-time computation of biological soft tissue deformations. We aim at developing a simulation tool for the planning of cryogenic surgical treatment of liver cancer. This therapy requires careful planning, therefore accurate modeling of the mechanical behavior of organs is required. Our method presently allows real-time computation of non-linear elastic tissue deformations, and further extension towards viscoelasticity modeling is planned.
