Large and round ablation zones with microwave ablation: A preliminary ...

Antenna design for microwave hepatic ablation using an ... 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. Large and round ablation zones with microwave ablation: A ... Microwave ablation (MWA) is a promising thermal therapy that uses heat to kill tumors. A large ablation zone with high circularity is desirable in clinical setting because most tumors are nearly spherical shapes. Single or multiple slot antennas are favored in MWA due to their good clinical outcomes, small dimensions and easy fabrication.

Aug 01, 2013 · Microwave ablation zones were created by using dual-slot and monopole control antennas for 2, 5, and 10 minutes at 50 and 100 W in ex vivo bovine livers. Dual-slot and monopole antennas were then used to create ablation zones at 100 W for 5 minutes in in vivo porcine livers, which also underwent intraprocedural imaging.
