In particular, the open issue of monitoring patients after stroke onset is addressed here in order to provide clinicians with a tool to control the effectiveness of administered therapies during the follow-up period. In this paper, a novel prototype is presented and characterized. The device is based on a low-complexity architecture which makes use of a minimum number of properly positioned and designed antennas placed on a helmet. It exploits a differential imaging approach and provides 3D images of the stroke. Preliminary experiments involving a 3D phantom filled with brain tissue-mimicking liquid confirm the potential of the technology in imaging a spherical target mimicking a stroke of a radius equal to 1.25 cm.<\/jats:p>","DOI":"10.3390\/s20092607","type":"journal-article","created":{"date-parts":[[2020,5,4]],"date-time":"2020-05-04T14:00:43Z","timestamp":1588600843000},"page":"2607","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":117,"title":["A Prototype Microwave System for 3D Brain Stroke Imaging"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4726-5017","authenticated-orcid":false,"given":"Jorge A.","family":"Tobon Vasquez","sequence":"first","affiliation":[{"name":"Department of Electronics and Telecommunications, Politecnico di Torino, 10129 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6363-9253","authenticated-orcid":false,"given":"Rosa","family":"Scapaticci","sequence":"additional","affiliation":[{"name":"Institute for the Electromagnetic Sensing of the Environment, National Research Council of Italy, 80124 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8520-906X","authenticated-orcid":false,"given":"Giovanna","family":"Turvani","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunications, Politecnico di Torino, 10129 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gennaro","family":"Bellizzi","sequence":"additional","affiliation":[{"name":"Department of Electric Engineering and Information Technologies, University of Naples Federico II, 80125 Naples, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0408-9308","authenticated-orcid":false,"given":"David O.","family":"Rodriguez-Duarte","sequence":"additional","affiliation":[{"name":"Department of Electronics and Telecommunications, Politecnico di Torino, 10129 Torino, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3990-9727","authenticated-orcid":false,"given":"Nadine","family":"Joachimowicz","sequence":"additional","affiliation":[{"name":"Group of Electrical Engineering-Paris (GeePs), CNRS, CentraleSup\u00e9lec, Universit\u00e9 Paris-Sud, Univ.
