In this work, we propose to measure and correct rigid body head motion using slab-selective FID navigators. It is possible to estimate motion without relying on any patient specific choreographic training by using simulated motion data and a forward model of FIDnav signal generation by including slab profile estimation. This calibration procedure provides a more practical solution, particularly for pediatric applications where subjects are unable to cooperate with specific instructions.
