A method for susceptibility-weighted imaging, which can enhance contrast of regions with high susceptibility in arbitrary slice orientation, was developed. To enhance contrast in arbitrary slice orientation clearly, this method uses a susceptibility map estimated by L1 norm regularization. In contrast to conventional methods, the proposed method can enhance contrast of veins and iron depositions without causing streaking artifacts in arbitrary slice orientation. A numerical simulation and experiments on healthy volunteers show this method can enhance contrast of regions with high susceptibility in arbitrary slice orientation.
