The finite sampling ofk-space in MRI causes spurious image artifacts, known as Gibbs ringing, which result from signal truncation at the border ofk-space.  ...  The method allows for a significant reduction of truncation artifacts without compromising resolution.  ...  Again, the ringing artifacts obtained for zero padding are significantly reduced when using TV-constrained data extrapolation.  ...

Gibbs-Ringing Artifact Removal Based on Local Subvoxel-shifts [article]

The origin can be seen in the truncation of k-space during MRI data-acquisition.  ...  Consequently, correction techniques like Gegenbauer reconstruction or extrapolation methods aim at recovering these missing data.  ...  Another modern approach consists of combined de-noising and ringing removal using using total variation constrained data exploration (6).  ...

Patch2Self: Denoising Diffusion MRI with Self-Supervised Learning [article]

Fluctuations from multiple sources create significant additive noise in DWI data which must be suppressed before subsequent microstructure analysis.  ...  By taking advantage of the oversampled q-space of DWI data, Patch2Self can separate structure from noise without requiring an explicit model for either.  ...  Acknowledgments and Disclosure of Funding We sincerely thank Prof. Qiuting Wen (Indiana University School of Medicine) for providing the simulated data used in the above experiment.  ...

Moreover, PFCS reconstruction of partially sampled data provided a better discrimination of hypoxic and oxygenated regions in a leg tumor compared to traditional CS reconstructed images.  ...  In order to capture oxygen variation in hypoxic tissues and localize cycling hypoxia regions, an accelerated EPRI imaging method with minimal loss of information is needed.  ...  The funders had no role in study design, data collection and analysis, decision to publish, or preparation of the manuscript.  ...
