Abstract
An elastography device includes a probe, to be held against the body of a subject, the probe including a single ultrasound transducer; or a plurality of ultrasound transducers, all ultrasound transducers of the being motionless with respect to each other, and a low frequency vibrator, arranged to induce a displacement of said single ultrasound transducer or plurality of ultrasound transducers towards a tissue to be characterized, and an electronic unit including an electronic circuit, configured to control the single ultrasound transducer or plurality of ultrasound transducers to emit a sequence of ultrasound pulses in the tissue to be characterized, and configured to acquire echo signals received by the single ultrasound transducer or plurality of ultrasound transducers in response to the ultrasound pulses emitted, in order to track how elastic waves travel in the tissue.
