A projected fat navigator module was added to a diffusion weighted EPI sequence to allow prospective rigid body motion correction without additional hardware. Improved image quality was demonstrated by imaging the brain of a volunteer subject who performed prescribed patterns of large motion with and without prospective correction. Improvements were most evident for through-plane motion. For in-plane motion only, the image quality was comparable to images acquired without motion. Ghosting due to gradient delays following FOV updates was avoided by acquiring phase reference lines directly after the excitation pulse.
