ENDOSCOPIC REGISTRATION OF VESSEL TREE IMAGES

摘要

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 (e.g., an arterial tree or a venous tree) within an anatomical region, and the endoscope controller (22) image registers the intra-operative endoscopic image (14) of the vessel tree to a pre-operative three-dimensional image (44) of the vessel tree within the anatomical region. The image registration includes an image matching of a graphical representation of each furcation of the vessel tree within the intra-operative endoscopic image (14) of the vessel tree to a graphical representation of each furcation of the vessel tree within the pre-operative three-dimensional image (44) of the vessel tree.
