For "bipolar" mode dixon method, we know that eddy current is serious when gradient polarity alternates quickly. For eddy current will misalign the k-space, which leads to a linear phase discrepancy for different echo image. The discrepancy will disrupt the chemical-shift induced phase difference,finally lead to the failure of fat water separation for dixon method. In this abstract, we represent a novel algorithm to correct the misalignment efficiently in image space.
