18 November 2014Influence trend of temperature distribution in skin tissue generated by different exposure dose pulse laser
Laser is widely applied in military and medicine fields because of its excellent capability. In order to
effectively defend excess damage by laser, the thermal processing theory of skin tissue generated by
laser should be carried out. The heating rate and thermal damage area should be studied. The
mathematics model of bio-tissue heat transfer that is irradiated by laser is analyzed. And boundary
conditions of bio-tissue are discussed. Three layer FEM grid model of bio-tissue is established. The
temperature rising inducing by pulse laser in the tissue is modeled numerically by adopting ANSYS
software. The changing trend of temperature in the tissue is imitated and studied under the conditions
of different exposure dose pulse laser. The results show that temperature rising in the tissue depends on
the parameters of pulse laser largely. In the same conditions, the pulse width of laser is smaller and its
instant power is higher. And temperature rising effect in the tissue is very clear. On the contrary,
temperature rising effect in the tissue is lower. The cooling time inducing by temperature rising effect
in the tissue is longer along with pulse separation of laser is bigger. And the temperature difference is
bigger in the pulse period.
