Breast Tissue Screening with Microwave Time-Domain Radar: Initial Clinical Trials

In this work, we present early results from a clinical trial of our time-domain microwave breast cancer screening system. The goal of the trial is to verify use of the system for a breast monitoring application. We follow four (healthy) patient volunteers and perform regular breast scans on them over a time period of eight months. We then compare the collected data and the reconstructed breast images from the scans. We show small variation in the signals collected from individual patients over time but also consistency in the corresponding images. Our results suggest that our system successfully avoids false positives over longer screening periods. The next step in our investigations is to determine if visible differences arise if malign tissue is present.
