Abstract

Screen (120) shows a digitized longitudinal view (134) and a key or scale (135) to show the colors or shades of gray corresponding to the spectral values. Cross section (136) shows a range of colors or shades of gray of different segments of the artery. The segment (136a) indicates that it is likely to be a normal segment. The segment (136b) is very light indicating a diseased tissue, likely to be highly vulnerable.
