1. A system comprising:
an imaging catheter configured to be positioned within a vessel comprising a vessel wall, wherein the vessel wall comprises a luminal border and a medial-adventitial border; and
a processing system operably coupled to the imaging catheter, the processing system comprising a processor coupled to a memory and a display device in communication with the processor, wherein the processing system is configured to:
receive, with the processor, imaging data obtained by the imaging catheter;
generate, with the processor, a plurality of cross-sectional image frames of the vessel based on the imaging data, wherein each of the plurality of cross-sectional image frames is a two-dimensional image frame;
receive, at the processor, a navigational input to navigate to a target cross-sectional image frame of the plurality of cross-sectional image frames;
automatically identify, with the processor, an outline of a vessel wall border of the vessel wall in the target cross-sectional image frame, wherein the vessel wall border comprises at least one of the luminal border or the medial-adventitial border;
calculate a numerical occlusion value based on the outline of the vessel wall border; and
display, with the display device, the target cross-sectional image frame, the outline of the vessel wall border overlaid on the vessel in the target cross-sectional image frame, and the numerical occlusion value.
