Figure 5

Effect of dynamic range, gain and probe distance on measured lumen diameter. Lumen diameter plotted against the dynamic range and gain settings used to record the images. Each data point represents the mean of 200 measurements. Error bars show standard deviation and if not visible are contained within the icon. The different symbols represent the distance between the ultrasound probe and the leading edge of the far war of the phantom artery. A. Phantom A with lumen diameter of approximately 4.98 ± 0.01 mm. B. Phantom B with lumen diameter of approximately 5.98 ± 0.01 mm. C. Phantom C with lumen diameter of approximately 4.98 ± 0.01 mm
