In the last twenty years, Microwave Imaging (MWI) has emerged as one of the most promising novel medical imaging modalities. With European researchers being at the forefront of MWI development of medical applications, the creation in 2013 of the Action network “MiMed” (Microwave MEDical) in the framework of the European cooperation in Science and Technology (COST) was welcomed with vivid enthusiasm. MiMed has polarised mostly independent research efforts into the design of several MWI devices. Such a reserve of knowledge and numerous initiatives carried by MiMed have constituted a unique opportunity for researchers to leverage existing experience and expertise to streamline the transition from simulation/phantom testing to full clinical trials and clinical adoption of MWI devices. Moreover, collaboration among participants has provided the support to overcome common challenges and bring MWI from “research bench to patient bedside”, boosting the European Research Area and its excellence in a worldwide context.
