Figure 7From: Validation of an arterial tortuosity measure with application to hypertension collection of clinical hypertensive patientsPhantom tortuosity curves. Helix phantom tortuosity curves are shown in maximum intensity projection. The pitch 5(2Ï€) (black), pitch 10(2Ï€) (red), pitch 20(2Ï€) (green) and pitch 40(2Ï€) (blue) phantoms decrease in tortuosity. (top) DFM tortuosity plotted versus distance d from the start. (bottom) DFM tortuosity plotted versus Length L from the start.Back to article page
