QSM is a method that generates internal susceptibility distribution of subject using material’s intrinsic magnetic susceptibility property. Bo inhomogeneity affects magnitude and phase images. In this study, QSM with B0 field inhomogeneity correction is proposed. Using numerical simulation and in-vivo experiment, proposed method is verified. In simulation, improved susceptibility map is obtained with less root mean square error. In in-vivo experiment, signal loss and non-uniformity at frontal lobe are reduced. As field inhomogeneity increases according to the increase of main field strength, this method would be a more important element for QSM.
