Coronary CT Angiogram cropped view over the right coronary artery (RCA, indicated by arrow) obtained at various intervals in the cardiac cycle using retrospective gating. Images obtained during the 70% phase minimize motion in this example. However, a priori estimation of the period and duration of this quiescent phase can be inaccurate using EKG alone.
