SYSTEMS, DEVICES, AND METHODS FOR COREGISTRATION OF INTRAVASCULAR DATA TO ENHANCED STENT DEPLOYMENT X-RAY IMAGES

A system includes a processor circuit in communication with an extraluminal imaging device and an intraluminal imaging device. The processor circuit obtains an enhanced stent deployment extraluminal image and a plurality of intraluminal images. The enhanced stent deployment extraluminal image and the each of the plurality of intraluminal images are associated with locations along a pathway. The pathway is overlaid over an extraluminal image. Based on the locations of the pathway, the processor circuit coregisters the plurality of intraluminal images to the enhanced stent deployment extraluminal image and outputs a screen display of one of the plurality of intraluminal images and the enhanced stent deployment extraluminal image with an indicator identifying the location at which the displayed intraluminal image was obtained. The processor circuit may also determine an expansion score for intraluminal images depicting the stent and identify regions of the stent corresponding to an expansions score below a threshold.
