Gibbs Ringing Correction for non-Cartesian Acquisitions
Motivation: Truncation in k-space leads to Gibbs ringing. Removal of Gibbs artifact for non-Cartesian isotropic sampling remains unaddressed. Goal(s): To develop Gibbs ringing correction method for non-Cartesian isotropic k-space readouts. Approach: We generalize the subvoxel-shift Gibbs ringing correction to isotropic sampling schemes. Results: The developed correction removes Gibbs ringing for isotropic sampling schemes. Impact: Gibbs ringing leads to artifacts and biases in parametric maps, especially in diffusion MRI. We generalize the subvoxel-shift Gibbs ringing correction, previously developed for cartesian EPI acquisitions, to non-Cartesian sampling. The method will increase the reproducibility of MRI processing pipelines.
