Abstract

The dynamic evolution of the coagulation front in laser irradiated prostate tissue is simulated using a nonlinear finite element method (NFEM) which takes into account the temperature and thermal damage dependence of blood perfusion rate and optical properties. Using this nonlinear model, it wasfound that the hyperemic ringformed at the periphery of the coagulationfront reduces heatpenetration significantly and the increased scattering near the tissue surface reduces the light energy deposition in the deep region. Thefinal damage depth would be overestimated by about 50% ifthe effect oftemperature and damage dependence of blood perfusion and opticalproperties modeling is disregarded.
