Abstract

Assessment of the severity of arterial disease is typically made using B-mode imaging for plaque evaluation and Doppler ultrasound for estimation of maximum blood velocity. Measurement of other blood velocity related quantities which are thought to be important in plaque development, such as wall shear stress, has proven difficult using conventional 2D ultrasound. This paper describes a 3D ultrasound system combined with computational fluid dynamics for estimation of 3D blood velocity and wall shear stress in arterial disease.
