Three-Dimensional Visualization Technology and Therapy Planning System for Microwave Ablation Therapy of Liver Tumor

Abstract

Three-dimensional (3D) visualization technology has been increasingly applied in image-guided therapy, and computerized 3D medical imaging is more intuitive and rich in anatomical details of minimally invasive therapy. Under the assistance of 3D visualization technology, 3D medical imaging can be displayed on the screen. Radiologists can perform various operations on 3D medical imaging (such as calculating, measuring, rotating, moving, scaling, hiding, and visualizing), so as to optimize the preoperative planning. Extensive experiments have been performed on phantom, porcine livers. Clinical researches also have been performed, and the actual necrosis zone is measured in postoperative contrast-enhanced CT images of patients. In the following chapter, the capabilities of 3D visualization technology are exploited for microwave ablation (MWA) of liver tumor by using a self-developed 3D computer-assisted therapy planning system.
