<table>Extraction of heart rate information. The location of the line of interest (LOI), (b), corresponds to the inlet of the geometric model for the CFD simulation (a). Based on the measured intensities (c), the time between subsequent intensity peaks (d) is used for estimating the patient’s heart rate.</table>
