Assessment of inversion strategies for microwave imaging of weak magnetic scatterers embedded into a biological environment

This communication deals with a recently proposed contrast enhanced microwave imaging methodology, which exploits Magnetite Nanoparticles as a contrast agent and relies on their capability to selectively reach malignant tissues as well as on their electromagnetic behavior in presence of a polarizing magnetic field. Since human tissues are non magnetic, such a microwave diagnostic tool faces cancer imaging as the reconstruction of a weak magnetic contrast hosted into an electric scenario. In this framework, the reconstruction capabilities of different inversion procedures are investigated and their robustness against uncertainties on the surrounding electric scenario and noise on data are compared.
