A method and apparatus of generating a hybrid three dimensional
reconstruction of a vascular structure affected by periodic motion is
disclosed. At least two x-ray images of the vascular structure are
acquired. Indicia of the phases of periodic motion are obtained and
correlated. Images from a similar phase of periodic motion are selected
and a three dimensional modeled segment of a region of interest in the
vascular structure is generated. A three dimensional volumetric
reconstruction of a vascular structure is generated that is larger than
the modeled segment. The modeled segment of interest and the volumetric
reconstruction of the larger vascular structure are combined and
displayed in human readable form.
