The numerical analysis of thermal process proceeding in biological tissue during a laser irradiation controlled by surface temperature of tissue is presented. Heat transfer in the tissue is assumed to be transient and one-dimensional. The internal heat sources resulting from laser irradiation based on the Beer law are taken into account. Perfusion rate and effective scattering coefficient are treated as dependent on tissue injury. At the stage of numerical computations the boundary element method has been used. In the final part of paper the results obtained are shown.
