9. Hiroshi Takamatsu, Is it possible to incorporate the effect of blood perfusion in apparent thermophysical properties for estimation of freezing in tissues?, 8th World Congress of Biomechanics, 2018.07, Estimation of temperature distribution in tissues and organs is critically important for medical treatments such as cryosurgery, hyperthermia and radiofrequency ablation which expose malignant tissue to temperatures extremely different from the physiological state. Commonly, the bioheat equation, instead of heat conduction equation, is used for estimation to incorporate the effect of blood perfusion, because the heat transfer in tissues is significantly affected by blood perfusion in addition to thermal transport properties of tissues. Nevertheless, in many cases, the rate of blood perfusion is not available for human tissues and organs. Furthermore, the thermophysical properties available from literatures have a large variation even in those measured in vitro without blood flow. These are the motivation of this study that aims to examine the feasibility of solving the normal heat conduction equation with apparent thermophysical properties to take the effect of blood perfusion into account. The temperature distribution was compared between the bioheat equation with given rates of blood perfusion and the heat conduction equation with apparent thermal conductivity or apparent heat capacity. Cooling and heating that induce no phase change were examined first in addition to a freezing case that simulates cryosurgery using a single probe. The result indicated that the simulation with the apparent thermal conductivity or specific heat capacity does not work for incorporating the effect of blood perfusion, although the temperature distribution inside a tissue looks similar if we assume an appropriate apparent heat capacity for a given blood perfusion. However, concerning only about the frozen region around the cryoprobe, the apparent thermal conductivity was useful: the growth of ice ball calculated from the bioheat equation agreed well with that obtained from the heat conduction equation if an appropriate value of thermal conductivity was used. The apparent thermal conductivity was determined only as a function of the rate of blood perfusion irrespective of time of freezing. The temperature distribution inside the ice ball is also predictable because no blood perfusion takes place in the frozen region..
