Invisible bifurcation detection within vessel tree images
First Claim
1. An image registration system, comprising:
- an endoscope (12) operable for generating an intra-operative endoscopic image (14) of a vessel tree within an anatomical region,wherein the intra-operative endoscopic image (14) of the vessel tree includes a plurality of branches of the vessel tree visible within the intra-operative endoscopic image (14) as an indication of a furcation of the vessel tree invisible within the intra-operative endoscopic image (14); and
an endoscope controller (22) operable for image registering the intra-operative operative endoscopic image (14) of the vessel tree to a pre-operative three-dimensional image (44) of the vessel tree within the anatomical region,wherein the image registration includes an image matching of a graphical representation of the furcation of the vessel tree as indicated by the visible branches of the vessel tree within the intra-operative endoscopic image (14) of the vessel tree to a graphical representation of the furcation of the vessel tree within the pre-operative three-dimensional image (44) of the vessel tree.

Abstract
An image registration system an endoscope (12) and an endoscope controller (22). In operation, the endoscope (12) generates an intra-operative endoscopic image (14) of a vessel tree within an anatomical region including a plurality of branches of the vessel tree visible within the intra-operative endoscopic image (14) as an indication of a furcation of the vessel tree invisible within the intra-operative endoscopic image (14). The endoscope controller (22) image registers the intra-operative operative endoscopic image (14) of the vessel tree to a pre-operative three-dimensional image (44) of the vessel tree. The image registration includes an image matching of a graphical representation of the furcation of the vessel tree as indicated by the branches of the vessel tree visible within the intra-operative endoscopic image (14) of the vessel tree to a graphical representation of the furcation of the vessel tree visible within the pre-operative three-dimensional image (44) of the vessel tree.
