Abstract:
Recent developments of ultrafast ultrasound
imaging scanners open very exciting possibilities
in the field of medical ultrasound. Thanks to the
new design of the most recent ultrasound scanners
that use a fully software-based ultrasound platform,
frame rates as large as 10.000 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 various innovations that leverage ultrafast
ultrasound imaging.
The first one is a new imaging mode that provides quantitative imaging of tissue elasticity by
following the propagation mechanical shear waves
with a spatial resolution and precision that were
never obtained with classical techniques. This is the
field of Shear Wave Imaging that shows many applications in cancer diagnostics, fibrosis evaluation
as well as cardio-vascular applications.
A second innovation is a 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 in vivo with ultrasensitive Doppler mode
will also be presented.
