Multiscale coherence regularization reconstruction using a nonlocal operator for fast variable-density spiral imaging

Multiscale coherence regularization reconstruction using a nonlocal operator for fast variable-density spiral imaging

Purpose Nonlinear reconstruction can suppress pseudo-incoherent aliasing artifacts from variable-density spiral (VDS) trajectories when interleaves are undersampled for acquisition acceleration during MR imaging. However, large-scale aliasing artifact suppression often conflicts with fine-scale str...
