The Forward-Backward Time-Stepping (FBTS) technique is applied to determine the presence and location of malignant tumor in the heterogeneous breast model. A new strategy is integrated in the FBTS algorithm to accurately estimate the dielectric properties of tissues. We demonstrate 2-D FBTS technique utilizing the numerical dispersive breast model in a free space. This new strategy manipulating Debye...
This paper presents recent advances in a 3-D inverse scattering technique, called forward-backward time-stepping (FBTS), applied to the reconstruction of the microwave properties of the breast. The FBTS algorithm is utilized for a numerical-based study of a 3-D breast model based on an MRI. Several illumination schemes, based on different microwave transmitter/receiver configurations, are compared...
In this paper, we present Forward-Backward Time-Stepping (FBTS) technique to determine the presence and location of malignant tumours in the breast model. We demonstrate 2-D FBTS technique utilizing the numerical breast model in a free space instead of immersed in coupling liquid. Numerical simulation results show the FBTS algorithm has the potential to provide useful quantitative information of the...
