Heat transfer in biological tissues

Abstract

The heat transfer process in biological tissues is studied through the Pennes bioheat equation, in dimensionless form, taking into account the temperature gradient delay by the Maxwell-Cattaneo model. Stochastic perturbations from the environment applied on the surface of the tissue and different external energy sources are considered. Comparison of temperature distributions with constant biological parameters are presented, from the skin surface and through the tissue transfer processes and to contribute to a better understanding on how nature works, it is essential to include biological, physical and biochemical.
