In Quantitative Susceptibility Mapping, susceptibility distribution can be obtained by deconvolution of perturbed fields with dipole fields. In our proposed method, High Resolution QSM, we employed densely sampled dipole fields to improve the quality of QSM. To verify the High Resolution QSM, we performed a human study, and acquired QSM input phase data of a healthy human subject. We compared MIP of the High Resolution QSM to that of the tricubically interpolated conventional QSM. In the High Resolution QSM, visibility of several cerebral blood vessels is improved. This means that a susceptibility map with higher spatial resolution is obtained.
