Abstract :
Mechanical properties of biological tissues exhibiting natural movements such as brain pulsatility or artery wall motion, and particularly tissue elasticity, can be estimated using ultrafast passive elastography processing. Indeed, determination of local tissue elasticity is becoming increasingly important in the diagnosis of tissue disease. In this work, we studied the shear wave propagation due to natural artery wall movement and evaluated the performance of two different methods to estimate local elasticity. The aim was to test the feasibility of measuring the Shear Wave Velocity (SWV) using an ultrafast ultrasound imaging system.
