Prospective and retrospective motion correction in diffusion magnetic resonance imaging of the human brain

► FID navigators detect motion and trigger non-weighted volume acquisition. ► Excellent detection performance of movements up to a sub-millimetre range. ► Diffusion scans are prospectively corrected, directional encoding stays coherent. ► Automatic repetition of motion-corrupted volumes. ► Can also be applied for highest diffusion weightings.
