Translational and rotational motion trajectories estimated from the EM tracking system and the proposed FIDnav motion measurement system during a volunteer scan where the subject was verbally instructed to perform a smooth, continuous (a) nodding motion and (b) shaking motion for the duration of the scan. FIDnav motion estimates are in good agreement with the ground truth motion values measured by the EM tracking system, with a slight trend for underestimation of larger amplitude motions.
