Reconstruction sensitivity to prior image quality. (a) Ground truth fully sampled time frame reconstructed using IFT. (b) Reordered rank constrained reconstruction with prior estimated using spatiotemporal TV reconstruction [Eq. (3)]. (c) Overly smoothed version of the STCR prior obtained with a spatial total variation filter. (d) Reordered rank constrained reconstruction using the smoothed STCR prior in (c). (e) Noisy version of STCR prior obtained by adding complex random Gaussian noise. (f) Reordered rank constrained reconstructions using noisy STCR prior in (e).
