EXPERIMENTAL STUDY ON RADAR-BASED BREAST CANCER DETECTION USING UWB ANTENNAS WITHOUT BACKGROUND SUBTRACTION

Abstract

An ultrashort-pulse radar using ultra-wideband (UWB) antennas such as compact Vivaldi antennas has been applied to the simulation experiment of breast cancer detection. A cooking-oil model and a commercial-made synthetic breast phantom model, which have been developed, as well as with real breast cancer patients during initial clinical trials have been used in our experiment. We detect the breast cancer tumor without using the background subtraction method. Image reconstructions of the breast models using reflection data have been performed by use of confocal microwave imaging (CMI) technique.
