Paper Abstract

This paper presents our work on the reconstruction of the complex permittivity 2-D profile of biological objects simulated as circular phantoms. An iterative reconstruction algorithm called the Levenberg-Marquardt method developed by Franchois and Pichot is tested using synthetic data. Assumed permittivity profiles are generated for a simple circular phantom using the CST microwave studio software. Then, we reconstruct the permittivity profile of the object in MATLAB by using the data from CST microwave studio. The main work in this paper focuses on the realization of the inversion algorithm on three different circular phantoms. Our results show that the permittivity profiles can be very satisfactorily reconstructed, thereby indicating the usefulness of this approach for medical diagnosis.
