A schematic of the reconstruction pipeline for real-time imaging with radial GRAPPA. Top: Highly accelerated radial k-space data are acquired for a high temporal resolution. Middle: Missing radial lines of data are reconstructed using through-time radial GRAPPA, where the weights are determined using the calibration scan. Bottom: Images are generated from the reconstructed fully-sampled radial data using NUFFT.
