Shear wave propagation induced by the acoustic radiation force is currently under investigation. In our experiments, an ultrafast scanner is used both to generate and detect shear waves propagation. The scanner is first used to focus, at a chosen location, a high intensity ultrasonic beam. The resulting acoustic radiation force induces in the focal zone a shear source. The system allows us then to apply very high ultrasound frame rates (up to 5000 images/s) in order to image the shear wave propagation, which velocity is linked to local elasticity properties of the medium. The elasticity map is recovered by solving the inverse problem. Actually, the generation of shear displacement requires high level insonifications at the threshold of FDA norms. Thus, the great advantage of such an ultrafast scanner is to recover the complete propagation by generating a unique palpation inside the medium. Measurements have been performed in several soft tissue mimicking phantoms with different elastic properties and in beef muscles. The 3‐D finite differences simulations have been used to support our experimental results: the delivered acoustic power and the resulting heating induced by the acoustic focused beam can be estimated and compared with the FDA requirements.
