[MRI] (영/한) Wrap around (aliasing) artifact / 엘리어싱 인공물
(영어/영문/English) Wrap around artifact? Anatomical structures outside the FOV appear inside the FOV, also called aliasing or fold over artifacts. These artifacts are generated when a FOV smaller than the size of the subject is selected and appear in either the frequency direction or the phase direction. (Also occurs in 3-D images) 1. Frequency wrap It occurs when the generated echo is under sampli..
