Brain stroke detection is becoming an important topic for the microwave imaging research community. In this work, we propose a quantitative method for detecting hemorrhagic brain strokes through the reconstruction of the dielectric permittivity distribution inside head. The associated nonlinear inverse scattering problem is iteratively solved by means of an inexact-Newton method. Preliminary numerical results, produced by applying the proposed method without a previous knowledge of the internal structure of the head, are presented and briefly discussed.

Abstract

Brain stroke detection is becoming an important topic for the microwave imaging research community. In this work, we propose a quantitative method for detecting hemorrhagic brain strokes through the reconstruction of the dielectric permittivity distribution inside head. The associated nonlinear inverse scattering problem is iteratively solved by means of an inexact-Newton method. Preliminary numerical results, produced by applying the proposed method without a previous knowledge of the internal structure of the head, are presented and briefly discussed.
