Forward-problem solutions were approximated using spherical-harmonic series on an adult male torso model with heart and lungs. These approximations were found using only a knowledge of torso-model geometry and were not based on a prior solution for surface potentials. Because these series depend only on polar and azimuthal angles, they allow continuous estimation of the forward-problem solution over the torso without further knowledge of the torso geometry. Compared to the conventional method… CONTINUE READING
