    Abstract

    For Electromagnetic Tomography (EMT) Techniques, image reconstruction is one of the crucial steps, which directly affects the quality of reconstruction and real-time performance of the EMT system. Following analyzing a pre-iterative method for SIRT (simultaneous iterative reconstruction technique) algorithm, a preconditioning for the projected SIRT is proposed to accelerate the image reconstruction speed and alleviate the ill-posed nature of the EMT inverse problem. Experimental tests confirm that the quality of the reconstructed images using the preconditioning algorithm is enhanced with only a small number of iterations required. © 2012.
