Magnetic susceptibility is an important physical property of tissues, and can be used as a contrast mechanism in magnetic resonance imaging (MRI). Recently, targeting agents by conjugation with signaling molecules labeling stem cells have become feasible. These are strongly paramagnetic, the ability to quantify could allow accurate measurement cell localization. Presented here technique estimate arbitrary distributions solving ill-posed inversion problem from field maps obtained MRI scanner....
