The derivation and application of the general characteristics of bioheat transfer for medical applications are shown in this paper. Two general bioheat transfer characteristics are derived from solutions of one-dimensional Pennes bioheat transfer equation; steady-state thermal penetration depth, which is the deepest depth where the heat effect reaches; and time to reach steady state, which represents the amount of time necessary for temperature distribution to converge to a steady-state. All results are described by dimensionless form; therefore these results provide information on temperature distribution in biological tissue for various thermal therapies by transforming to dimension form.
