Paper Abstract

A non-stationary two-dimensional computer code for modelling of radiation and heat transport in heterogeneous biological tissues irradiated with laser is presented. Radiation transport is considered in the kinetic model, radiation transport equation is solved by the Monte Carlo method. Heat transport is considered in the heat conduction model, the heat equation is solved by a combination of Galerkin and the finite element methods. The code has passed a number of tests including comparisons with analytical solutions, numerical calculations of other authors, and with experimental results. The code can be used for working out and designing of laser surgical and therapeutic procedures. As well it can be used in inverse problem of experimental determination of optical and thermal parameters of biological tissues.
