Design and Preliminary Evaluation of a superficial applicator for hyperthermia with a new coaxially fed antenna: Theoretical models

This paper describes 3 different stages: Modeling, Construction and Preliminary Evaluation of a superficial applicator, with a new coaxially fed antenna, for its use in oncology hyperthermia treatments. Modeling stage was developed by the Finite Element Method, using Maxwell and Bioheat equations; here, antenna dimensions were optimized. In the second stage, the optimized applicator was constructed in aluminum and copper, taking in count results achieved in the modeling stage. Finally, it was characterized for its clinical use. SWR, incident and reflected waves and calorimetric measurements are presented in this paper.
