FIGURE 5.

Representative images and the ASDs between the automatic and manual methods for the seven arterial segments. On the left, the first column represents the original cross-sectional slices reconstructed from MR vessel wall images, the second column represents the automatically segmented lumen contour and outer vessel wall contour, and the third column represents the manual segmentation results of lumen and outer vessel wall contours of the seven arterial segments. The red contour represents the lumen, and the green contour represents the outer vessel wall. The ASDs of the seven arterial segments are shown on the right using a bar plot. The standard deviation (SD) represents the amount of dispersion of the variable and is calculated as the root square of the variance. ASD, average surface distance.
