Automatic contour detection algorithm for carotid artery quantification. Automatic contour detection algorithm for carotid artery quantification. The endoluminal surface indicated by a green circle was automatically detected. Stent struts were manually traced and positioned in the center of the stent strut. The lumen, stent, and neointimal (stent − lumen) area were measured. Maximum and minimum thickness on magnification was automatically measured (black and white arrows). Yoshikazu Matsuda et al.
