A novel phantom with dia- and paramagnetic substructure for quantitative susceptibility mapping and relaxometry

PurposeA phantom is presented in this study that allows for an experimental evaluation of QSM reconstruction algorithms. The phantom contains susceptibility producing particles with dia- and paramagnetic properties embedded in an MRI visible medium and is suitable to assess the performance of algorithms that attempt to separate isotropic dia- and paramagnetic susceptibility at the sub-voxel level.MethodsThe phantom was built from calcium...
