Time Reversal Based Microwave Hyperthermia Treatment of Breast Cancer

Abstract

In this correspondence, a new time reversal (TR) based ultra-wideband (UWB) microwave method for hyperthermia treatment of breast cancer is presented. Two high-resolution techniques, time reversal (TR) and robust Capon beamformer (RGB), are employed to shape the transmitted signals both temporally and spatially. As shown in the two-dimensional (2D) numerical simulations, this method has better electromagnetic (EM) energy focusing ability than the existing methods, and can provide the necessary temperature gradients required for effective hyperthermia
