Figure 4From: Magnetic resonance velocity imaging derived pressure differential using control volume analysisComputed volume flow rate waveform. Volume flow rate waveform, computed from PC-MR velocity data obtained in the phantom. Qk, in mL/min, was calculated using Equation (3) within the ROI shown in Figure 3(c) during a single cycle in msec. Flow into the phantom is positive. Dotted line displays sinusoidal fit.Back to article page
