The motion in diffusion imaging was more accurately estimated using simulated diffusion images rather than the b=0 images because the simulated diffusion images had the same contrast as the diffusion images. For diffusion imaging with a single shell b this method has been confirmed to be effective without extensive iteration even for a large amount of deliberate motion. Furthermore, this method has been extended to account for multiple exponential diffusion weighting in diffusion spectrum imaging where the b value ranges widely.
