8-shot brain diffusion-weighted images (resolution = 0.85 × 0.85 × 3 mm3, b-value = 1000 s/mm2, nex = 1) reconstructed by POCS-ICE (a), shot-LLR (b) and POCS-ICE with shot-LLR as initialization (c). Figure 2a, 2b and 2c have the same window level. The yellow arrow shows aliasing artifacts in POCS-ICE. The curve (d) shows values of the cost function used in POCS-ICE and the horizontal axis is the iteration axis. Using shot-LLR as initialization makes the algorithm converge much faster and to a better local minimum.
