Recent developments of ultrafast ultrasound imaging scanners open very exciting possibilities in the field of cardiovascular imaging. Thanks to the new design of the most recent ultrasound scanners that uses a fully software-based ultrasound platform, frame rates as large as 20.000 frames/s are reached today. Compared to classical ultrasound scanners that delivered some 100 frames/s these new possibilities represent a complete breakthrough. We will describe at least three innovations that leverage ultrafast ultrasound imaging. The first one is a new imaging mode that provides quantitative viscoelastic analysis of arterial wall by following the propagation of both pulse waves and shear waves with a spatial resolution and precision that were never obtained with classical techniques. The second one allows to image in a very quantitative way the cardiac elasticity anisotropy by studying shear wave propagation in different directions. The last innovation is new way to perform Doppler flow analysis, from ultrafast scanners, changing completely the performances and workflow paradigms of Color and PW modes. Various results obtained with these techniques in the field of cardiovascular imaging will be presented.
