Comparison of phase‐constrained parallel MRI approaches: Analogies and differences

Phase‐constrained parallel MRI approaches have the potential for significantly improving the image quality of accelerated MRI scans. The purpose of this study was to investigate the properties of two different phase‐constrained parallel MRI formulations, namely the standard phase‐constrained approach and the virtual conjugate coil (VCC) concept utilizing conjugate k‐space symmetry.
