ABSTRACT: This paper
proposes a new holographic microwave imaging array (HMIA) technique for brain
stroke detection. This approach is based on holographic microwave and aperture
synthesis imaging techniques. The system is designed for operation at a single
frequency of 2.5 GHz. A realistic three dimensional (3D) head model that
contains skin, fat, skull, cerebrospinal fluid (CSF), grey matter, white matter
and ischemic or hemorrhagic stroke area is developed using MATLAB to
demonstrate the proposed HMIA imaging algorithm.A matching solution medium is used between the
antennas and the head model. The study is conducted using HMIA computer
simulations and 3D head model with-stroke.The simulation results showed that small stroke area (5
mmin diameter) could be successfully detected with the HMIA
approach.
