Microwave Ablation Antenna for Functional Adenomas in the Adrenal Gland

Abstract

Microwave thermal ablation has been thoroughly investigated in the last decades. However, new challenges for this technology are nowadays represented by specific applications. The present work investigates a promising ablative solution for the treatment of functional adenomas in the adrenal gland. In this paper, a numerical study conducted to build and test an optimized internally cooled triaxial antenna is presented. The antenna has been designed to minimize its transversal dimension merging radiating and cooling elements. The proposed antenna has been then built in our laboratories and experimentally tested on ex vivo biological tissues. Numerical and experimental results will be reported and discussed.
