Figure 4 Peak systolic and end-diastolic velocity data from the common carotid artery of one volunteer. Blood velocity data from the cross-sectional vessel area are shown as function of their distance to the center of the vessel lumen. Open circles are the velocity data used for the 3DP fit (0.3 to 1.3 mm from vessel wall). The two-dimensional projection of the resulting 3DP is shown as solid lines. n = number of pixels.
