[Dynamics of temperature changes in tissues during laser irradiation].

Dynamics of heat wave propagation from irradiated surface into the tissue was studied. Computation of our results and those of other authors proved that temperature distribution against the tissue depth proceeds according to Buger law. Quenching coefficient values of the heat wave are calculated. This coefficient features more completely biophysical properties of the tissue, than the temperautre gradient. Tumour and pigmented tissues have a higher quenching coefficient of the heat wave as compared to normal and unpigmented tissues.
