Its therapy principle lies in injecting of liquid nitrogen or argon into cryoprobes and inserting them into tissue to destroy tumor in low temperature. In the process of the cryosurgery, it is necessary to consider the size and location of tumor to decide the localization and the number of cryoprobes. However, the approach to freezing tumors thoroughly and minimizing the cryoinjury to the surrounding health tissues is still an important research target.
Therefore, this research analyzes the difference between the rapid-iceball-simulation and the practical simulation of the iceball. According to the different time interval of cryosurgery, the software, ESI-CFD, is utilized for bioheat transfer equation and mesh generation technology of the ANSYS ICEM CFD is to calculate the increasing rate of the two iceball of the rapid-iceball-simulation, the overlapping rate between them, and the volume of the iceball in order to compare with their results, and figure out their difference. It is believed that the results from this research can supply valuable data to clinicians as a reference of real cryosurgery.
