Paper Abstract

The monitoring and control of the thennal dose in non-contact laser hyperthermia treatment of tumors requires a model and solution of the lasertissue interaction. Presented are two models for the thermal response of tissue during continuous wave, noncontact, laser hyperthermia treatment of tumors. The first model is where all the laser energy is absorbed at the surface of the tissue and the second model is where the laser energy penetrates into the tissue before absorption. Both models include the effect of blood perfusion in the solution for the temperature rise. It is shown that perfusion has a negligible affect on the temperature distribution for the surface absorption of laser energy. However, in the case of laser energy penetration, perfusion has a significant effect which increases with increasing optical penetration.
