Three-dimensional two-point Dixon technique has been routinely used for liver imaging to provide opposed and inphase images, as well as fat only and water only images. Phase partial Fourier and strong echo asymmetry are often employed to reduce the scan time. However, echo asymmetry and phase partial Fourier with zero filling result in blurring artifacts in the in-plane view. This abstract describes the use of phase correction with projection onto convex sets (POCS) to the three dimensional two-point Dixon sequence in order to reduce blurring artifact and improve image quality at short scan times
