Mathematical Modeling of Temperature Distribution on Skin Surface and Inside Biological Tissue with Different Heating

Abstract

Aim of the paper is to investigate thermal behaviors in living tissues subject to constant, sinusoidal, step surface heating and point or stochastic heating with the thermal model of bioheat transfer which are often encountered in cancer hyperthermia, laser surgery, thermal comfort analysis and tissue thermal parameter estimation etc. The Pennes bioheat transfer equation, which describes the exchange magnitude of heat transfer between tissue and blood, is widely used to solve the temperature distribution for thermal therapy. The analytical solution of bioheat transfer equation is determined by using Green's function method with surface heating conditions which describes the transient temperature response on the skin surface and inside the biological tissue. It is observed that the thermo mechanical behavior of skin tissue is very complex; blood perfusion has little effect on thermal damage but large influence on skin temperature distribution. © 2009 International Federation of Medical and Biological Engineering.
