To evaluate carotid lumen segmentation results on bifurcation geometry quantification, bifurcation angle and mean centerline distance were calculated. The intra-class correlation coefficient (ICC), linear regression and Bland-Altman plot of bifurcation angle, as well as the mean centerline distance indicated that the segmentation results had strong correlation with golden standard. The segmentation results could be used on geometry quantification.
