Experiment with in-vivo human brain data (Slice 38): (a) Body-coil image corresponding to fully-sampled phase-encode; (b) Poisson-disk-based k-space sampling pattern (on a Cartesian grid) with 84% undersampling (black spots represent sample locations); (c) Square-root of SoS of coil images obtained by taking inverse Fourier transform of the undersampled data after filling the missing k-space samples with zeros (also the initial guess x(0)); (d) the solution x(∞) to P0 in (2) obtained by running MFISTA-20; (e) Absolute difference between (a) and (d) indicates that aliasing artifacts and noise have been suppressed considerably in the reconstruction (d).
