<p>An NMR data set (310, 311) which is acquired at (218) with applied phase encoding and read-out gradients at (136) is corrected to reduce motion artifacts and increase image sharpness. The acquired NMR data set (310, 311) is examined at (100) to detect bulk displacements of the object being imaged and phase displacements caused by motion. This information is employed to produce correction operators (330, 331, 337) which are applied to the NMR image data set. One or more navigator signals (340) may also be acquired at (218) during the scan to produce an NMR data set from which the corrective operators can more readily be derived.</p> |
