Synopsis

The gibbs-ringing (also known as "truncation artifact" or "spectral leakage" ) is a result from reconstruction if images from a finite (bounded) k-space. It results in oscillations according to the sinc function in the vicinity of sharp image gradients at tissue boundaries. In this presentation, examples of the artifact are illustrated and simulations are shown to understand it better. Finally, correction strategies are discussed.

Gibbs-ringing is a well-known artifact in the form of oscillations in the vicinity of sharp image gradients at tissue boundaries. In this presentation, examples of the artifact are illustrated and simulations are shown to understand it better. Finally, correction strategies are discussed.
