Abstract: The disclosure relates to methods of providing live x-ray images such as fluoroscopic images in combination with reference information co-registered angiography frames that are motion corrected in real time. In part, the disclosure describes an improvement on the existing workflow where the user must remember where the vessel features from OCT are and use a reference frame to estimate the location of desired stent placement. Disclosed herein are methods to correlate the live imaging feed and the reference angiography image such that the user may dynamically zoom and pan the live imaging feed and the reference angiography image.

Abstract: In part, the disclosure relates to systems and methods to assess stent/scaffold expansion in a vessel on an expedited time scale after stent/scaffold placement and expansion. In one embodiment, the method generates a first representation of a stented segment of the blood vessel indicative of a level of stent expansion; determines using the detected stent struts, a first end of the stent and a second end of the stent; and generate a second representation of the segment of the blood vessel by interpolating a lumen profile using an offset distance from the first end and the second end.

Abstract: In one aspect, the invention relates to a computer-implemented method of triggering optical coherence tomography data collection. The method includes collecting optical coherence tomography data with respect to a vessel using an optical coherence tomography probe disposed in the vessel; determining a clearing radius and a quality value for each frame of optical coherence tomography data collected for the vessel using a computer; determining if a blood clearing state has occurred using at least one clearing radius and at least one quality value; and generating a trigger signal in response to the blood clearing state.
