Abstract

Computed tomography (CT) data (28) is collected for a plurality of slices by a CT scanner (10). At least a portion of the CT data is reconstructed (32) to form a volume image (34) defined by a plurality of two-dimensional image slices. At least one starting point is identified (72) within a blood vessel imaged in the three-dimensional image volume (34). The blood vessel is recursively tracked (70) to form a blood vessel representation (92).
