Radar-based Imaging through StrokeWave Device: Preliminary Experimental Results

This paper presents for the first time, preliminary measurement results obtained using an innovative microwave brain imaging device, named StrokeWave. Brain strokes are the world’s second largest cause of death and the largest cause of adult disability, and their correct timely detection is vital for increasing patient’s chance of survival. The StrokeWave prototype introduced here employs only two antennas which operate without matching medium, and uses a radar backpropagation algorithm based on the Huygens’ principle. We present results obtained through both a cylindrical phantom and the head of a patient with hemorrhagic stroke who participated in our first round of clinical trials. Our measurement results indicate the capability of the algorithm in detecting and localizing the dielectric contrast, paving the potential for brain stroke detection and classification.
