In this paper, a microwave approach for brain stroke imaging is discussed. The developed technique relies on a Newton iterative scheme performing a regularization in Lebesgue spaces with non-constant exponent, which takes advantage of the simultaneous processing of multiple frequencies to enhance the reconstruction quality. The effectiveness of the approach is evaluated considering numerically simulated data concerning realistic 3D phantoms.

Abstract
In this paper, a microwave approach for brain stroke imaging is discussed. The developed technique relies on a Newton iterative scheme performing a regularization in Lebesgue spaces with non-constant exponent, which takes advantage of the simultaneous processing of multiple frequencies to enhance the reconstruction quality. The effectiveness of the approach is evaluated considering numerically simulated data concerning realistic 3D phantoms.
