Statistical analysis of carotid images from atherosclerosis patients and healthy volunteers, using mean intensity ratio of the target ROI and the reference region. (a-b) Intensity ratio of the reconstructed images at 800 nm using (a) prior-integrated or (b) standard reconstruction. (c-d) Intensity ratio of the reconstructed images at 930 nm using (c) prior-integrated reconstruction and (d) standard reconstruction. ns: difference between two groups is not significant, p > 0.05; **: difference between two groups is very significant, p < 0.01.
