In this paper, a microwave imaging method is proposed for brain stroke detection. In particular, the developed imaging procedure is based on an iterative Gauss-Newton scheme and it is aimed at determining the presence of a hemorrhagic brain stroke. Interrogating microwaves are used in a multistatic and multiview arrangement. Preliminary numerical results concerning the reconstruction of a simulated stroke inside a two-dimensional slice of the human head are reported. A numerical model is used to obtain the synthetic data used in the inversion process through the solution of a forward electromagnetic scattering problem, which is performed under transverse magnetic conditions.
