Shear wave imaging was evaluated for the in vivo assessment of myocardial biomechanical properties on ten open chest sheep. The use of dedicated ultrasonic sequences implemented on a very high frame rate ultrasonic scanner (>; 5000 frames per second) enables the estimation of the quantitative shear modulus of myocardium several times during one cardiac cycle. A 128 element probe remotely generates...
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...
ShearWavetrade Elastography (SWE) is a new real time ultrasound imaging mode that quantitatively measures local tissue elasticity in kPa. Based on the Supersonic Shear Imaging concept (developed at the Laboratoire Ondes et Acoustique, Paris), this new concept may appear as a promising tool to improve breast lesion characterization. In vitro experimental measurements have been performed to quantify...
