This paper proposes a 2-step image reconstruction method in which the nonnegativity
constraint in the iterative maximum-likelihood expectation maximization (MLEM) algorithm is …

The aim of this paper is to propose a partitioned-image filtering technique that is a new way
of reducing the Gibbs phenomenon in filtered images. Methods: This technique relies on …

Gibbs ringing is a well known artifact that effects reconstruction of images having
discontinuities. This is a problem in the reconstruction of magnetic resonance imaging (MRI) …

Purpose To develop a fast and stable method for correcting the gibbs‐ringing artifact.
Methods Gibbs‐ringing is a well‐known artifact which manifests itself as spurious …

In Magnetic Resonance Imaging (MRI), the K-space data is often under-sampled and
truncated to shorten the scan time. However, the truncation of K-space also causes Gibbs …

An iterative algorithm that involves image filtering and data replacement (as suggested by
Constable and Henkelman) is investigated for reducing the Gibbs artifact in magnetic …

Gibbs artifact in magnetic resonance imaging results when band‐limited interpolation is
used. This is typically done when there are more reconstructed pixels in the phase encoding …

Gibbs ringing artifact is a type of image distortion which manifests itself as spurious ringing
around sharp edges. It is an inevitable result of truncating the Fourier Series due to missing …

Gibbs ringing creates artefacts in magnetic resonance images that can mislead clinicians.
Reconstruction algorithms attempt to suppress Gibbs ringing, or an additional ringing …

The finite sampling of k-space in MRI causes spurious image artifacts, known as Gibbs
ringing, which result from signal truncation at the border of k-space. The effect is especially …
