Abstract

Thermal analyses of biological tissues irradiated to laser-induced heat source were studied by using thermal wave model of bio-heat transfer and the Pennes model. As a model, two concentric layers of spherical tissues, a diseased tissue and a healthy tissue, with various thermal physical properties were simulated and thermal wave model of bio-heat transfer equations were solved by a hybrid scheme combined the differential transformation method and finite difference method. Three types of surface heating problems were analyzed. Finally, the thermal variations were simulated in spherical coordinate and the interface between the diseased tissue and healthy tissue of the model. Comparative studies on the traditional Pennes equation and thermal wave model of bio-heat transfer were performed and evaluated. Furthermore, temperature variations in tumor exposed to laser-induced heat were predicted depending on heat flux, elevation temperature, decaying factor and thermal relaxation time.
