OCT attenuation imaging of a coronary artery with an atherosclerotic lesion in vitro. (a) and (b) OCT image and corresponding histology of the artery. (c) Cartoon overlaid on the histology to indicate an advanced necrotic core (red) behind a calcification (gray), and a slight fibrotic (green) circumferential intimal thickening. (d) OCT attenuation coefficient image ranging from 0 (blue) to $15{\mathrm{mm}}^{-1}$ (red). Scale bar: 1 mm. Adapted from Ref. 16.
