A New Impulse Train to Cancel Zipper Artifacts in the MRI

摘要：

Based on the mechanism of production of zipper artifacts in the MRI in the process of the spin-echo sequence imaging, we find a new impulse sequence which can dispel zipper artifacts obiviously. The result is that zipper artifacts can be cancelled thoroughly in the echo with instantaneous gradient in a range of 90 to 120 degrees when we write this new sequence.
