Traces from vNavs during MPRAGE with jaw motion of an otherwise still subject. For accurate brain-motion correction, the detection must be insensitive to structures other than the brain. Siemens’ real-time registration PACE detected large head motion when the subject moved their jaw. FLIRT with brain masks estimated substantially reduced translations and almost no rotations. FLIRT only is shown for comparison. Note that FLIRT’s execution time would be incompatible with real-time use.
