Hybrid artifact removal for breast imaging applied to a time-domain microwave system

Abstract

In this paper, we demonstrate the successful use of a hybrid artifact removal algorithm for microwave breast imaging when applied to a time-domain system. This algorithm, previously applied to VNA-based prototypes, combines two existing algorithms to remove the early time response primarily due to the direct pulse between antennas, and the skin response. We discuss the modifications necessary to this previously developed algorithm to correctly extract the tumour response signal for our time-domain system. We also compare post-processing results for simulation and experimental data.
