Microwave hyperthermia system for head and neck area with noninvasive UWB temperature change detection (original) (raw)

2017 Progress In Electromagnetics Research Symposium - Spring (PIERS), 2017

Abstract

The main topic of this contribution is the design and demonstration of combination the hyperthermia applicator system for head and neck area working on frequency 434 MHz with UWB radar antenna array for differential temperature detection. For our numerical simulations, the simplified homogenous phantom and 3D numerical model of patient were used. For two-dimensional reconstruction of reflected signals the Delay and Sum beamforming algorithm were used. The phantom was locally heated up using the microwave hyperthermia applicator and the temperature distribution was used as an inhomogeneity (through change in relative permittivity and specific conductivity). The results confirm the feasibility and usability of temperature change detection via UWB signal in the head and neck area.
