Suppression of MRI Truncation Artifacts Using Total Variation Constrained Data Extrapolation
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 visible for acquisitions at low resolution and commonly reduced by filtering at the expense of image blurring. The pre...
