Abstract :
A method for the three-dimensional (3-D) tracking and the quantitation of blood vessels from magnetic resonance imaging (MRI) is discussed. The approach is based on the 3-D geometrical moments and consists of the following steps: (1) interactive selection of 3-D seed points, (2) automatic tracking of the vessels, (3) local computation of both diameter and orientation, and (4) rendering of the vessel approximation model. The results on simulated and real data depict a good behavior of the detection and estimation scheme
