WebA phase-contrast cine produces images that represent velocity as a function of time in the cardiac cycle. Before we performed quantitative analysis of flow within a region of interest, we estimated a constant baseline for that region by calculating the average throughout the cardiac cycle of the apparent velocity in a neighboring static structure.
