Abstract :
A novel 3D numerical model reproducing the acoustic behavior of human vessels is presented. The model, based on a right generalized cylinder (RGC), enables the representation of various vessel structures, including bifurcations, and the associated pathologies. Examples of simulated B-mode and Doppler images are presented to show the capabilities offered by the model.
