Abstract
A simulation-experiment method is proposed to characterize the performance of a realistic microwave ablation (MWA) device. Ex-vivo porcine livers are used in the study. The catheter is modeled without understanding its electrical structure or the actual ablation power; so, it is adaptable to other ablators. The optimized 3-D finite difference time domain (FDTD) simulation can efficiently reflect the lesion profile in heterogeneous tissues and is clinically beneficial. This method can serve as a guideline to evaluate the device performance and the treatment plan. The influence of the temperature dispersive dielectric and the thermal properties has also been discussed.
