A novel suscepibility mapping method based on compressed sensing is proposed, in which the ill-conditioned k-space regions are estimated using compressed sensing. No prior knowledge of the underlying susceptibility map is required. Much lower lelvel of streaking artifacts are received comparing to the direct threshold method using in vivo brain data set.
