Abstract
A method for segmenting a vessel from an image data that includes accessing the image data from which the vessel is segmented through a user display interface. A first seed point is then received from a user, the first seed point placed by the user on a first location on the image data. A second seed point is further received from the user, the second seed point placed by the user on a second location on the image data. The method further includes calculating a centerline for the vessel to be segmented, the centerline beginning at the first location and finishing at the second location as indicated by the first and the second seed points, respectively; calculating borders of the vessel to be segmented based on the centerline; and displaying an output of the vessel to be segmented using the centerline and the borders of the vessel, wherein the calculating the centerline comprises utilizing a minimum cost dual front propagation method that incrementally accumulates local vessel measures to determine a global optimal cost path and form the centerline.
