Multi-channel non-Cartesian phase contrast imaging has been demonstrated with great capability for various 4D flow MRI applications. However, reconstruction latency has been challenging, as well as the need for a robust phase preserving coil combination algorithm. Among several recently reported algorithms, the Direct Virtual Coil (DVC) technique provides great potential to address both challenges simultaneously. This work is to demonstrate the usage of the DVC technique for non-Cartesian phase-contrast imaging, specifically, PC-VIPR.
