Method and system for registering intra-object data with extra-object data

Abstract

Methods for correlating intraluminal data with x-ray image data involve 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 the 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 wire within the x-ray image. A corresponding system and computer program are also disclosed. The method and systems can be controlled by one or more computer systems configured with specific executable instructions.
