Figure 1

Three-panel view of a single 3-D color flow acquisition reproduced in a flow phantom for a carotid (panels A to C) volume flow profile. The acquisition shows the pulsatile nature of the observed flow. The three panel types shown are: (A) axial-lateral view, (B) axial-elevational view and (C) elevational-lateral view. The schematics below (B) illustrate the spatial relationship of the three views; here (a) corresponds to (A), etc. All three panels coincide at the center point that is labeled in (A) and marked in each view. The pulsatility of carotid flow leads to the acquisition of blue bands in the elevational direction (B) in the observed vessel due to the finite time of the volumetric acquisition of the mechanical probe used. (D) shows the averaged velocity from 21 acquisitions as shown in (C). Averaged (linear) Doppler power is shown in (E).
