Abstract: The present disclosure provides systems and methods for dynamically visualizing the delivery of a device within a vessel by correlating at least one first extraluminal image with second extraluminal images. The extraluminal images may be correlated based on motion features, without the use of other sensors or timestamps. The first extraluminal image may be a high dose contrast x-ray angiogram (“XA”) and the second extraluminal images may be low dose contrast XAs. The high dose contrast XA may be used to generate a vessel map. The low dose contrast XAs may be taken during the delivery of a device, such as a balloon, stent, probe, or the like. Correlating the high dose XA and low dose XA based on motion features allows for the vessel map to be overlaid on the low dose XA to provide the physician visualization of where the device is within the vessel tree in real time.
