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
