Figure 4

Representative images for optical coherence tomography analysis. (A) Representative optical coherence tomography (OCT) images for O type subjects. (B) Representative OCT images for non-O type subjects. A0 and B0 show longitudinal section of vessel and the length of white line is the length of plaque. A1 and B1 show the cross-section image of minimum lumen. A2 and B2 show the cross-section image of lipid-rich plaques with minimum fibrous cap thickness. A3 and B3 have enlarged the measurement site of fibrous cap thickness.
