Post-occlusive blood flow velocity in the femoral artery in a 25 year-old male. a) Magnified view of a velocity image reconstructed from velocity-encoded projections during the early phase of hyperemia after the cuff deflation (background cropped). The time axis and the readout direction are indicated and each vertical line represents a velocity profile obtained from a pair of velocity-encoded projections. b) time-course of blood flow velocity (region of red rectangle magnified in panel c). The duration of forward flow Tff is indicated by the double arrow. The magnification in c) shows that each spike corresponds to a systolic peak.
