Freezing of Biological Tissues During Cryosurgery Using Hyperbolic Heat Conduction Model (original) (raw)

This paper considers hyperbolic heat conduction model for biological tissue freezing during cryosurgery with non ideal property of tissue, metabolism and blood perfusion. Mathematical model is solved numerically using nite di erence method to obtain temperature distribution and phase change interfaces in tissue dur- ing freezing. The e ects of phase lag of heat ux in hyperbolic bio-heat model on freezing process are studied. Comparative study of parabolic and hyperbolic bio-heat models is also made here.
