We propose and develop a method to separate paramagnetic and diamagnetic components within one voxel based on a 3-pool signal model. Alternating between solving for linear and nonlinear parameters in the model, paramagnetic component susceptibility (PCS) and diamagnetic component susceptibility (DCS) maps are constructed to represent the sub-voxel compartments.
