Integrated RF and Cryo ablation of liver tumor for computer integrated surgery

Abstract

Recent research shows combining Radiofrequency (RF) and Cryosurgery could improve the outcome of tumor treatments. Reasons for combining RF and Cryo includes: (1) producing maximal destruction while maintaining hemostatic control; (2) reinforcing the tissue destruction; (3) inducing anti-tumor immune response. For large liver tumor treatment, multiple insertions of electrodes are always required and computer planning is needed to achieve optimally planned ablation. This study investigates the effectiveness of combined RF and Cryo ablation in computer planning of large tumor ablation.
