Abstract
We propose the application of a two-step iterative shrinkage/thresholding method (TwIST) to improve the resolution in microwave imaging applications. The TwIST algorithm is combined with the distorted Born iterative method (DBIM) to reconstruct the complex permittivity of two-dimensional (2-D) anatomically realistic numerical breast phantoms. The paper discusses how to optimize the algorithm parameters in order to improve the quality of reconstructions and the robustness of the algorithm. Our results demonstrate the ability of this method to produce images with enhanced resolution in two-dimensional (2-D) microwave breast imaging.
