REDUCTION OF MOTION ARTIFACT IN NMR IMAGES USING SPHERICAL NAVIGATOR SIGNALS
摘要
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.
