Brain stroke is a leading cause of death and a significant contributor to adult disability. To reduce its damaging effects resulting from brain cell death, it is fundamental to start appropriate treatment as soon as possible, making an early and accurate diagnosis critical. Ideally, the diagnosis should be rapid and, if feasible, performed directly in the ambulance or at the trauma site. Microwave Imaging (MWI) can be an alternative to traditional diagnostic techniques like Computed Tomography and Magnetic Resonance Imaging, which both have drawbacks. MWI is safe due to the non-ionizing nature of the electromagnetic waves used, making it suitable for ongoing monitoring.
