1. A system comprising:
an imaging catheter comprising an image capture device at a distal portion of the imaging catheter, wherein the imaging catheter is configured to capture, via the image capture device, imaging data associated with a vessel of a patient while the imaging catheter, including the image capture device, is positioned within the vessel, wherein the vessel comprises a vessel wall comprising 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, the imaging data;
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;
for each of the plurality of cross-sectional image frames:
automatically detect, with the processor, a location of a vessel wall border of the vessel wall, wherein the vessel wall border comprises at least one of the luminal border or the medial-adventitial border;
determine an outline of the vessel wall border based on the detected location of the vessel wall border; and
store the outline of the vessel wall border in the memory;
receive, at the processor, a navigational input to navigate sequentially through the plurality of cross-sectional image frames;
sequentially display, with the display device, the plurality of cross-sectional image frames in a manner representing motion through the vessel, while the navigational input is received; and
in response to a cessation of the navigational input:
stop the sequential display of the plurality of cross-sectional image frames at a target cross-sectional image frame, wherein the target cross-sectional image frame is a cross-sectional image frame, of the sequentially displayed plurality of cross-sectional image frames, that was being displayed at the time of the cessation of the navigational input;
retrieve, from the memory, the outline of the vessel wall border for the target cross-sectional image frame; and
display, with the display device, the target cross-sectional image frame and the outline of the vessel wall border overlaid on the vessel in the target cross-sectional image frame.
