COMSOL Multiphysics® is a simulation platform based on the finite element method. The program covers the entire modeling workflow from the definition of geometries to the simulation of complex physical processes.
In various laser treatments, laser light is absorbed by tissue, causing it to heat up. Temperature diffusion distributes this heat into surrounding tissue. This results in temperature profiles that vary spatially and temporally in a laser-induced manner. To understand the effect of laser treatments on tissue, laser radiation, subsequent tissue absorption and resulting temperature diffusion can be simulated. This allows statements to be made about clinically relevant laser parameters. Furthermore, laser-induced pressure propagation can be simulated.
