Microwave Imaging (MI) provides a low-cost and safe approach to the non-invasive diagnosis of biological structures. However, solving the associated Inverse Scattering Problem (ISP) in a timely manner poses several challenges. To jointly achieve high reconstruction accuracy and low computation time, an imaging strategy based on the System-by-Design (SbD) paradigm is presented. The proposed SbD approach can deal with ISPs with an inhomogeneous background and is capable of exploiting a-priori information on the electromagnetic (EM) characteristics of the biological structure under investigation. Preliminary results based on a realistic brain phantom show that a remarkable reconstruction accuracy is achieved together with a significant reduction in terms of computation times as compared to competitive state-of-the-art approaches.
