1. A method of generating a hybrid three dimensional reconstruction of a vascular structure affected by periodic motion, the method comprising: placing an object affected by periodic motion to be imaged in an imaging region of an x-ray system, the object having a vascular structure; acquiring at least two x-ray images of the vascular structure; obtaining indicia of the phases of periodic motion and correlating the indicia with each of the at least two x-ray images; selecting at least two x-ray images from a similar phase of periodic motion; generating a three dimensional modeled segment of a region of interest in the vascular structure, the modeled segment reconstructed using the selected x-ray images from a similar phase of periodic motion, the region of interest only a portion of the imaged vascular structure; generating a three dimensional volumetric reconstruction of a vascular structure larger than the modeled segment; combining the modeled segment of interest and the volumetric reconstruction of the larger vascular structure; and displaying in human readable form the combined reconstructed vascular model and volumetric reconstruction.
