Computer Modeling for Microwave Ablation in Breast Cancer Using a ... Microwave energy is a promising alternative treatment because it can preferentially heat and damage high-water-content breast carcinomas. In order to evaluate the feasibility of using this technique to treat breast cancer, a coaxial slot antenna computer simulation based on an axisymmetric finite element method (FEM) model was used to compare heating differences between cancer and normal breast tissue. Three FEM computer models were developed: in one of them, the coaxial slot antenna was ... Open Access Coaxial Slot Antenna Design for Microwave Hyperthermia ... Coaxial Slot Antenna Design for Microwave Hyperthermia using Finite-Difference Time-Domain and Finite Element Method ... A computer modeling of a double slot antenna for interstitial hyperthermia was designed us-ing two different numerical methods, the Finite Element Method and a Finite-Difference Time-Domain. The aim of this work is to analyze both numerical methods and finally experiments results are compared to the simulated results generated by a thermal model. Our results show that ... Antenna design for microwave hepatic ablation ... - PubMed Central (PMC) Antenna design. Several antenna designs have been shown to be effective for the treatment of deep-seated hepatic tumors. Recently, Saito et al presented a design for a double slot antenna that is capable of achieving a higher degree of SAR localization than a standard single slot antenna and has been used in initial clinical trials. Feasibility of Using a Novel 2.45 GHz Double Short Distance Slot ...
