Abstract

A 2-D Pennes' bioheat transfer mathmatical model was presented to study the temperature spatial distribution and its time dynamic characteristic of human skin tissue irradiated by He-Ne laser. The non-linear bio-heat transfer equation was solved by use of finite element analysis method. The temperature distribution simulation results in radial and axial direction at different time was obtained. The effect of different laser power and the blood perfusion rate on the temperature distribution of skin tissue was analyzed. This research method maybe provides possibility to predict thermal damage of clinic laser surgery, and is helpful to inspect curative effect and choose medical laser parameters.
