UWB MICROWAVE IMAGING FOR BREAST CANCER DETECTION --- EXPERIMENTS WITH HETEROGENEOUS BREAST PHANTOMS

Abstract

The paper describes pulse-based ultra-wideband (UWB) radar microwave imaging experiments for breast cancer detection using breast phantoms with dielectric properties mimicking the human breast. Three homogeneous and seven heterogeneous breast phantoms are designed with a series of dielectric permittivity and variability and are used in tumor detection experiments. The experiments are conducted in time-domain with pulse generator and real-time oscilloscope.
