Abstract

Green's functions of the response of a medium to a single external stimulus were used to model the propagation of optical radiation in biological tissues and scattering media. The algorithm makes it possible to take into account the multilayer character of the medium, the finite size of the incident beam, and also the interaction of the surface of the tissue with the external medium. A solution of the thermal-conductivity equation using the method of finite elements is presented, the temperature fields are calculated that arise when biological material is irradiated with low-intensity laser radiation at various instants, and graphs are also constructed to show how the temperature depends on the time at which the material is irradiated with constant and pulsed action.
