Channel-by-channel (CBC) data-driven parallel imaging may suffer from long computation times for multi-phase dynamic imaging, which can limit its utility in a clinical setting. This is particularly problematic with high channel counts, large parallel imaging factors and large matrix sizes. This work demonstrates the feasibility of a recently developed Direct Virtual Coil (DVC) technique to reduce the computation time for parallel imaging in dynamic imaging applications.
