3 out of 30 directions 8-shot diffusion-weighted images (columns i-iii, resolution = 0.85 × 0.85 × 3 mm3, b-value = 1000 s/mm2, nex = 2), and corresponding fractional anisotropy (FA) maps color-encoded by the principal diffusion tensor eigenvector (V1) (column iv) of different methods. Inaccurate phase estimation leads to erroneously estimated DTI V1 (Fig. 3ab, column iv, blue regions highlighted by arrows) and a loss of structural details (Fig. 3ab, column iv white boxes). Shot-LLR initialized POCS-ICE reduces artifacts in POCS-ICE, and also removes shading from shot-LLR.
