Gibbs ringing artifacts are bright or dark lines that are seen parallel and adjacent to borders of abrupt intensity change. The ringing is caused by incomplete digitization of the echo. This means the signal has not decayed to zero by the end of the acquisition window, and the echo is not fully digitized. 4, record 1, English, - truncation%20artifact

L'artefact de troncature apparaît sous la forme d'une alternance de lignes parallèles d'intensités différentes, se répétant à intervalles réguliers. Cet artefact survient dans le sens du codage de phase, au niveau d'une zone de transition brutale du signal entre deux structures. Il est dû à un échantillonnage incomplet de l'écho et donc à une mauvaise restitution de cette variation abrupte de signal. 2, record 1, French, - art%C3%A9fact%20de%20troncature
