ABSTRACT
BACKGROUND:
An axisymmetric finite element method (FEM) model was employed to demonstrate important techniques used in the design of antennas for hepatic microwave ablation (MWA). To effectively treat deep-seated hepatic tumors, these antennas should produce a highly localized specific absorption rate (SAR) pattern and be efficient radiators at approved generator frequencies. METHODS ANDRESULTS:
As an example, a double slot choked antenna for hepatic MWA was designed and implemented using FEMLABtrade mark 3.0.DISCUSSION:
This paper emphasizes the importance of factors that can affect simulation accuracy, which include boundary conditions, the dielectric properties of liver tissue, and mesh resolution.
