Claim 14:
15. The method of claim 14, wherein one or more of the following:
(i) in a case where the NIRAF signal is provided simultaneously with an OCT image, both the lumen to catheter or probe distance step(s) and the correction step(s) are applied in real time; and/or
(ii) image construction and/or reconstruction includes:
(a) importing A-lines and corresponding NIRAF values from an OCT-NIRAF apparatus or system;
(b) correcting the NIRAF values according to a distance of the catheter or probe from the lumen border or borders; and
(c) performing image processing, and/or performing image processing include at least: transforming the A-lines of each frame to 2D OCT images and transforming the corrected NIRAF signal to an overlaid ring around OCT.
