FIGURE 3:

(a) Velocity magnitude map of a sagittal cut of the stenotic phantom distal to the throat or region of interest during systole. Qmax = 150 ml/s (range: 100.0 cm/s to 0.0 cm/s. (b) Velocity magnitude map in diastole for the same study (range: 100.0 cm/s to 0.0 cm/s). (c) Velocity magnitude map of the aortic arch phantom with a 0% calcification synthetic valve at peak systole (Qmax = 150 ml/s). The valve is located on the lower left portion of the picture; the high-speed jet may be seen immediately distal to the valve (range: 100.0 cm/s to 0.0 cm/s). (d) The same sagittal slice as in (c), but during diastole (range: 100.0 cm/s to 0.0 cm/s). (e) peak systolic axial slice of velocity magnitudes corresponding to (c) and immediately distal to the valve. The valve opening clearly visible with its trileaflets (range: 175.0 cm/s to 0.0 cm/s). (f) Corresponding diastolic axial slice of velocity magnitudes (range: 50.0 cm/s to 0.0 cm/s).
