Abstract
The present work that extends the study in the literature to that laser irradiation is highly absorbed in the biological tissue and analyzes the problem based on the generalized dual-phase-lag model. A hybrid application of the Laplace transform and the modified discretization technique are used to solve the generalized dual-phase-lag model of bioheat transfer with the pulse boundary heat flux. The effects of the coupling factor between blood and tissue, porosity, and the phase lag times on the results are investigated. Comparison between the present results and the results in the literature is made and exposes some interesting phenomena. Results show that the generalized dual-phase-lag model has different temperature evolution from the classical DPL model and the Pennes equation and cannot reduce to the Pennes bio-heat transfer equation for τq=τT, even τq=τT=0s.
