Short axis views of the heart together with whole R-R interval time series of one-dimensional projections along the profile (dotted line) marked in the short axis view. Data were obtained at 7.0 T using ECG (left), pulse oximetry (middle) and acoustically triggered (right) 2D CINE FLASH acquisitions. ECG triggered CINE imaging was prone to severe cardiac motion artifacts due to R-wave misregistration. Acoustically triggered CINE imaging at 7.0 T produced images free of motion artifacts.
