Claim 20:
21. A system for registering x-ray images with intraluminal data of a tubular organ comprising:
an angiographic imaging apparatus for obtaining x-ray images of the tubular organ;
an intravascular apparatus for obtaining intraluminal data of the tubular organ; and
a combination device comprising a data processing module, and interface elements for receiving x-ray images from the angiographic imaging apparatus and intraluminal data from the intravascular apparatus,
wherein the data processing module is configured to synchronize the x-ray image data with the intraluminal data based on a cardiac cycle extracted from an available input signal and/or the x-ray image data and/or the intraluminal data to match x-ray image data with intraluminal data in a specific cardiac phase and co-register the x-ray image data with intraluminal data by creating a cumulative image at the specific cardiac phase which reconstructs a path followed by an intraluminal wire used for acquiring the intraluminal data to link the intraluminal data to spatial locations of the path followed by the intraluminal wire within the x-ray image, wherein the co-registration of the x-ray image data with the intraluminal data involves determining a start of pullback of the intraluminal wire by analyzing a movement curve created by computing absolute distance of the intraluminal wire between a reference image frame and remaining image frames of the x-ray image data.
