heal.abstract	The feasibility of using the Generalized Matrix Inversion scheme and iterative algorithms known as Algebraic Reconstruction Techniques in the reconstruction of simulated functional brain images and Event-Related Potentials (ERP) measured at the scalp is evaluated. Various models are tested with respect to a number of ERP discrete sources and voltage measurement points. Results indicate that the ART4, when combined with underrelaxation, is the most reliable algorithm for reconstructing brain images in noisy environments.	en
