Phase based MR-EPT methods mainly make use
of the balanced SSFP since it is a fast MRI sequence. As SSFP sequence yields
high magnitude contrast variations, Gibbs artifacts occur at tissue boundaries.
This artifact manifests itself as phase spikes and oscillations at and near
tissue boundaries respectively. The commonly used image enhancement methods,
for reducing the ringing artifact, mainly focus on the magnitude images,
leaving out the phase images. Throughout simulation and phantom experiment
results, we investigate and propose a method for the reduction of the effect of
ringing artifact on phase based MR-EPT studies.
