Microwave Radar Imaging as a Tool for Medical Diagnostics

Abstract

Microwave radar imaging is a diagnostic technique that is receiving significant attention in the research community for the striking advantages it may potentially offer. Nonetheless, diagnosis via microwave radar imaging is extremely difficult due to theoretical as well as practical reasons. In this contribution, in particular, we focus on the need to take frequency dispersion effects and the antenna’s frequency response into account. In more detail, we propose an imaging algorithm that works by completely ignoring the tissue frequency behaviour as well as the antenna’s response. The numerical results obtained via a full-wave electromagnetic solver for a simplified breast layout confirm the potential of the proposed approach.
