Abstract

Microwave hyperthermia is a promising method of cancer treatment used to increase the temperature within the interval of 40 - 44degC. The goal of this paper is to introduce the possibility of treatment planning for superficial hyperthermia using COMSOL Multiphysics. The real model of the patient with recurrent breast cancer was developed. The waveguide horn applicator with aperture of 10 x 10 cm was used for the planning. Results of impedance matching and 3D SAR distribution are presented.
