Application of the multiplicative regularized contrast source inversion method to real biological data

In this paper we applied the so-called Multiplicative Regularized Contrast Source Inversion (MR-CSI) method for imaging of real biological microwave tomography data. By using this method we show that the inversion of three-dimensional high contrast biological object which involves 175616 complex dielectric permittivity unknowns is feasible with a present day computer power.
