Slot antenna for microwave ablation

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. A coaxial slot antenna with frequency of ... - SpringerLink

A tissue ablation system for treating fibrillation in a patient comprises a steerable interventional catheter having an energy source that emits a beam of energy to ablate tissue thereby creating a conduction block for aberrant electrical … US4475108A - Electronically tunable microstrip antenna - Google The microstrip antenna or radiator used for microwave transmission and receiving is conventionally known in the art to comprise a planar or curved radiating element of a specific shape and size overlaying and separated from a ground plane. Levels of detail analysis of microwave scattering from human Similarly in the case of a complex location 2, the E-Norm absolute difference between both head models at the center of stroke circle was calculated as 0.04236 V/m and the same was maximum as well. 2018 IEEE International Symposium on Antennas and Propagation Antenna-Based Carpet Device FOR Extremely Large Obstacles: Experimental Verification

An axisymmetric electromagnetic model of the double slot choked antenna used for hepatic microwave ablation (MWA). (a) FEM model. (b) Logarithmic SAR distribution. Results were normalized using the maximum SAR obtained.

Coaxial Slot Antenna Design for Microwave Hyperthermia using A computer modeling of a double slot antenna for interstitial hyperthermia was designed using two different numerical methods, the Finite Element Method and a Finite-Difference Time-Domain. Evaluation of a Novel Thermal Accelerant for Augmentation of For the thermal ablation trials, a 915 MHz SynchroWave ST microwave antenna (Perseon Co., Salt Lake City, UT) or a 2.45 GHz SurBlate microwave antenna (Vison Medical USA Inc.
