## Abstract A method of correcting motional artifacts in diffusion‐weighted images is described. Motion causes changes in the phase of the __k__‐space NMR signal and thereby introduces positional shifts (or ghosts) in the spatial domain. By correcting the phase of the NMR signal before Fourier tran
