Multimedia File 1. Ultrasound imaging of transverse view of pulsating left common carotid artery (CCA) in the neck. Diameter changes can be measured from this series of images to assess the vessel mechanical properties. The electrocardiogram (ECG) signal is at the bottom of the image.
Multimedia File 2. Simulated wave propagation after application of acoustic radiation force excitation. The result is a three-dimensional response for a tube with fluid inside and surrounding the tube. Waves propagate down the length of the tube as well as around the circumference.
