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 ). |
