Facing the "Curse of Dimensionality" in MW Medical Imaging towards Real-World Applications

The application of microwave (MW) imaging in real-world medical scenarios requiring high-resolution reconstructions of highly-contrasted targets is addressed. The arising curse of dimensionality imposed by the large number of unknowns poses significant challenges to be faced in satisfying both performance and reliability requirements. A novel solution approach based on the System-by-Design (SbD) paradigm is presented to attain accurate reconstructions at a limited computational cost. The proposed method is validated in a preliminary numerical experiment using realistic phantoms of breast tumors.
