Application of the multiplicative-regularized Gauss-Newton inversion for microwave biomedical imaging applications

In this work the authors applied the MR-GN approach for solving 3D problems at microwave frequency for biomedical imaging applications. This MR-GN technique has also been applied for 2D transverse magnetic (TM) data by Mojabi and Lo Vetri. By using this MR-GN inversion approach we will show that there is no need to determine the regularization weight and the approach can also preserve sharp edges by employing the weighted L2-norm regularization.
