Abstract

This chapter introduces a three-dimensional (3D) visualization navigation system and its clinical application in preoperative planning, intraoperative positioning, and postoperative assessment during microwave ablation of liver tumors, respectively. Compared with two-dimensional preoperative planning group, the 3D visualization preoperative planning group has a higher successful rate of first ablation and less number of sessions. The 3D visualization navigation system has the advantage of image fusion in commercial navigation system; in addition, 3D visualization image will provide more information for microwave ablation and enhance ablation efficacy and decrease the complication. In postoperative assessment, 3D visualization navigation system could visually and quantitatively display the postoperative efficacy of microwave ablation in liver cancer. Therefore, the 3D visualization navigation system has a relatively high clinical application value in the whole process of microwave ablation for liver cancer.
