Slot antenna for microwave ablation

antenna was used. Conclusion: The dual-slot microwave antenna created a more spheri-cal ablation zone than did the monopole antenna both in vivo and ex vivo liver tissue. Greater control over power delivery can potentially extend the advantages of the dual-slot antenna design to higher power and longer treatment times. qRSNA, 2013 NEUWAVE™ Microwave Ablation System - Ethicon Inc.

A Dual-Slot Microwave Antenna for More Spherical Ablation … 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. MEASUREMENTS, ANTENNA DESIGN AND ADVANCED … MEASUREMENTS, ANTENNA DESIGN AND ADVANCED COMPUTER MODELING FOR MICROWAVE TISSUE ABLATION Deshan Yang Under the supervision of Prof. John G.

With reference to FIG. 1, a microwave ablation (MWA) antenna 100 is connected to and fed by a coaxial cable 102 that provides electromagnetic energy to antenna 100 at a selected operating frequency f 0. MWA can be used to provide thermal therapy for treatment of various types of cancer 108 in various tissue/organs 106.

The purpose of this model is to compute the radiation field and the Specific Absorption Rate (SAR) in liver tissue for a thin coaxial slot antenna used in microwave coagulation therapy. A simulation of the resulting temperature distribution in the liver is also included. Antenna Performance Simulation of a Probe for Thermal ...
