In this abstract, we report the use of NMR probes for prospective motion corrections of head motion in high-resolution gradient echo (GRE) imaging at high field of 7 Tesla. 3 NMR probes mounted on a volunteers head are used in conjunction with a linear navigator sequence to measure and correct for head motion in real time. The system is evaluated with 1 mm³ isotropic voxel GRE scans with a series of motion patterns on normal volunteers. Effective real time compensation is demonstrated for each type of motion tested.
