Fast multi-static technique for microwave brain imaging

A fast microwave imaging method for brain stroke detection is presented. The method estimates the power distribution of the scattering waves inside the head based on the measured multistatic scattered signals around the head. In that regard, Average Trace Subtraction (ATS) and Bessel function are used to remove the background reflections and calculate the scattering electromagnetic waves in the frequency domain. The imaging algorithm is verified using a round-shaped 8-element antenna array which surrounds a realistic head model in the simulation environment. The obtained images using the presented technique demonstrate its ability in brain stroke detection and localization.
