Patent ID: 7356367

Claim:
A computer based method of visualizing a region using multiple image data sets comprising: acquiring first volumetric image data of a region; acquiring at least second volumetric image data of the region; determining structural features of the region using the first volumetric image data determining at least one control point in the region using at least one structural feature in the first volumetric image data; identifying the at least one control point in the region in the at least second image data of the region; registering the first image data and the at least second image data using said at least one control point; fusing the registered first image data and at least second image data into a common display data set; and wherein the region includes a branched structure having a common section and at least two branches extending from the common section forming a bifurcation region and wherein a bifurcation point is determined as the center of an imaginary maximal diameter sphere which is fit within the bifurcation region.
