Abstract

A method and appertaining system permit a co-registration between points in a three-dimensional model of a vessel and vascular images obtained by an imaging catheter within the vessel at the respective points. The three-dimensional model is created by utilizing information from at least two external two-dimensional images produced by, e.g., one or more x-ray devices. The three-dimensional model is displayed on an analysis workstation, and a user may view the vascular images at particular points by selecting the appertaining points on the three-dimensional model.
