Multi-shell diffusion imaging from the Human Connectome Project. B0 images from L/R phase encoding (a) and R/L phase encoding (b) show the images were distorted in opposite phase encoding directions due to susceptibility in the magnetic field. (c) Corrected B0 image after removing susceptibility-induced distortion and merging the data from L/R and R/L phase encodings. Multi-shell diffusion imaging acquires data from several b-values. For the gradient directions along the x axis, the images from b=1000, 2000, 3000 s mm⁻² are shown in (d–f), respectively. Note the greater attenuation in the image intensity with an increased b-value.
