Temperature Distribution in Biotwarns Dynamics Modeling

Abstract

A widely used way to model the propagation of laser beams in biological tissues is by 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 a wavelength of . A mathematical model of the heat transfer process, based on the solution of the differential equations through the finite element method, was introduced. A mathematical model was developed to describes the processes of heat transfer, based on an analytical solution of a system of equations that describe the dynamics of electronic and atomic subsystems. 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.
