One of the widely used ways to model the spread of laser beams in biological tissues is through the Monte Carlo method. This article focuses on the distribution of temperature in human skin based on the results of the Monte Carlo method for a laser beam with а wavelength of 800nm. A mathematical model of the heat transfer process, based on the solution of the differential equations through the finite element method, was introduced. Simulations of the laser beam diffusion and the distribution of temperature in the skin were performed for two types of beams. The results of this work can be used to make an assessment of the energy levels of pulse laser treatment with different durations, during which a damage of biological tissue is observed, as well as to create standards for the safe use of laser systems.
Keywords: biological tissues, Monte-Carlo method, laser.
