Modelling of the clinical 9.2GHz MEA applicator

Abstract

This thesis describes the analysis of temperature distributions produced by a 9.2GHz microwave applicator, via computational and experimental modelling techniques. This applicator is currently used for a clinical treatment known as Microwave Endometrial Ablation. The computational modelling uses commercial software packages, based on the Finite Element Method, together with in-house computer programs to perform combined electromagnetic and thermal analyses of the applicator. Results from these analyses are then validated by the experimental measurement of temperatures, in phantom tissue, produced by heating from the applicator. Computational and experimental modelling is then used to investigate denaturation caused by the applicator to biological materials. Finally, a new variant of the applicator is proposed for treating other medical conditions. As well as being modelled computationally and experimentally, the histological effects of using this new applicator to heat excised human skin tissue are investigated.
