We developed attenuation imaging in OCT for atherosclerotic tissue characterization and validated the method ex and in-vivo. We introduced an en-face map of attenuation in the whole artery for plaque visualization. We quantified the attenuation derived from OCT and derived an index for the plaques.
A single centre clinical study (OC3T study) was conducted to validate the index to identify thin cap fibroatheromas. We also demonstrated the utility of the attenuation maps and the index in clinical studies as corresponding well with a visual assessment of LCP in the OCT data by expert readers .
