Paper Abstract

The Monte Carlo method of statistical simulations was used to evaluate the effects of anisotropic scattering and refractive index mismatch at the boundaries of the medium on light and temperature distribution in the multilayered biotissues during laser irradiation. The influence of optical parameters of multilayered tissue on its stationary thermal response was examined by using an adaptive version of finite element solution of the heat conduction equation. Calculations were performed for two models of human skin and adjacent tissues for visible (five layer model) and UV (three layer model) ranges of wavelengths. The topic of this paper is especially pertinent to laser percutaneous irradiation of blood and laser PUVA therapy.
