  • Reduction of motion artifact in NMR images using spherical navigator signals
    Patent number: 7127092
    Abstract: A series of fMRI image frames are acquired along with interleaved navigator signals. The navigator signals are acquired while three orthogonal readout gradients are applied such that a spherical surface is sampled in k-space. The navigator signals are analyzed to measure subject rotational and translational motion during the scan.
    Type: Grant
