Abstract
A method for labeling vessel branches forming first and second vessel systems. A 3D image is segmented to obtain vessel branches. First and second root points are then determined. Starting from the first root point, the vessel branches are traced to derive a tracing path and a break point is determined, that separates the tracing path into two portions. A region of interest in the 3D image is determined with respect to the break point, in which center lines are assigned to the first or second vessel system. A 3D cutting structure is generated based on distances measured from points on the center lines to the 3D cutting structure. Graph representations are constructed for the first and second vessel systems. The vessel branches are labeled with different labels based on the graph representations.
