For the time limit, "Bipolar" mode gradient used for three point dixon method on high field MR system will result in the k-space misalignment for the cause of eddy current. And the misalignment will bring addition phase in image space,which will contaminate the chemical-shift phase, and lead to the failure of fat water separation. This abstract adapt a novel methods which correct this kind k-space misalignment through dealing with the phase discrepancy in image space.
