Regularization method for phase-constrained parallel MRI

Purpose To implement a regularization method for the phase‐constrained generalized partially parallel acquisitions (GRAPPA) algorithm to reduce image artifacts caused by data inconsistencies. Methods Phase‐constrained GRAPPA reconstructions are implemented through the use of virtual coils. To that e...
