We have recently shown that a previous unknown longitudinal movement and a corresponding longitudinal strain are present in the arterial wall. The objective of this study was to introduce and evaluate an improved method for measurement of the longitudinal movement as well as to show results from the first in vivo trial of measurement of the shear induced longitudinal elastic modulus of the arterial...
The concept of shear wave elasticity imaging is applied to arteries. The goal of this study is to demonstrate the potential of this technique for precisely and non-invasively quantifying the elasticity of the arterial wall. Experiments are performed in arterial phantoms composed of elastic cylindrical shells that have an elastic modulus in the range of human arteries stiffness. The feasibility of...
The objective of this study was to show a method that combine non-invasive measurements of the relative diameter change, the radial and the longitudinal strain of the intima-media complex of arterial walls, respectively, to obtain total change in arterial wall volume for a segment of the common carotid artery. The method was evaluated in a limited trial in vivo, comprising five normotensive subjects...
