摘要：
Motion artifacts are selectively suppressed in an image by correcting only the NMR data in the central views. The peripheral views are not corrected with the result that motion artifacts produced by large objects in the image are suppressed while motion artifacts produced by small objects are not. Consequently, the interior of small blood vessels remain darker in the reconstructed image.
