ABSTRACT:
An NMR image data set is acquired along with interleaved navigator signals. The navigator signals are acquired while two, orthogonal readout gradients are applied such that a circular orbit in k-space is sampled. The navigator signals are analyzed to detect object motion and to produce corrective values for the NMR image data to reduce artifacts caused by object rotation and displacement along two axes.
