Stroke detection based on variations in reflection coefficients of wideband antennas

In this paper, we investigate the possibility of using array of wideband antennas to differentiate between the two kinds of brain stroke: ischemic and hemorrhagic. Wideband antennas arranged as a circular array surrounding a human head and immersed in a coupling medium are used to monitor a suspected stroke area. The proposed method is based on comparing the reflection coefficients of any pair of antennas located symmetrically around the head. The simulated results indicate a promising method of using the variation in the reflection coefficient of the antennas to give a quick differentiation between different head strokes, which is a must for any possibility of a patient survival.
