Plots of measured AAo ejection period, and computed fmax99, minimum required temporal resolution, and minimum required cardiac phases in S2 PC-CMR acquisitions against heart rate. Black circle = patients with structurally normal heart, open circle = additional patients with various clinical indications, AAo = ascending aorta, Ejection period = foot-to-foot distance of AAo blood waveform, fmax99 = frequency below which 99% of the total signal energy of the waveform is contained, S2 = SENSE acceleration factor of 2
