Abstract
Cryosurgery is a surgical technique that applies a low temperature source into the human tissue so as to remove the tumor. Cryosurgery includes several heat transfer mechanisms such as blood perfusion, phase change, and metabolic rate. Blood perfusion affects the size of the ice ball during cryosurgery. Commonly, the bio-heat equation needs to be solved to consider the blood perfusion effect. The objective of this study is therefore to investigate the possibility of using an effective thermal conductivity instead of solving the bio-heat equation. Based on the calculated temperature distribution, the effective thermal conductivity can be used under certain conditions.
