Illustration of rank constrained reconstruction with perfect reordering. (a) Fully sampled data with IFT reconstruction. One diffusion encoding direction is shown. (b) Corresponding R = 4 IFT reconstruction. (c) Corresponding R = 4 standard low-rank reconstruction. (d) Corresponding R = 4 low-rank reconstruction with reordering. [(e)–(h)] Same as [(a)–(d)] but for a time frame in a perfusion dataset.
