Abstract :
Vector Doppler ultrasound (VDUS) systems offer the potential for improved accuracy in mapping of complex flow parameters, such as recirculation, turbulence and shear stress, which are probable risk factors leading to vascular disease and stroke. VDUS system configurations with 2 to 6 receivers and corresponding reconstructions of a complex velocity field were numerically evaluated.
