Claim 0:
1. A method for correlating intraluminal data with x-ray image data, comprising:
providing x-ray image data of a tubular organ;
providing intraluminal data of the tubular organ;
synchronizing 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-registering 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 coregistering 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.
