摘要： A probe for transient elastography includes a probe casing, at least one ultrasound transducer having a symmetry axis, a vibrator located inside the probe casing, a position sensor coupled to the probe casing, the position sensor being arranged to measure the displacement of the probe, wherein the vibrator is arranged to induce a movement of the probe casing along a predefined axis, the predefined axis being the symmetry axis of the ultrasound transducer. The ultrasound transducer is bound to the probe casing with no motion of the ultrasound transducer with respect to the probe casing, and the probe includes a feedback circuit including the position sensor and a control loop and configured to use the displacement of the probe as a feedback signal and to control the movement of the vibrator inside the probe casing and the shape of a low frequency pulse applied by the probe.

摘要： A system for characterizing tissue includes a probe that delivers a continuous and periodic mechanical vibration to a tissue of a subject; an ultrasound emitter that emits a sequence of ultrasound shots and an ultrasound receiver that receives corresponding echo signals to track how the tissue is moved by the periodic mechanical vibration delivered to the tissue; and a control module programmed to provide homogeneity information to an operator of the system, the homogeneity information being determined from at least some of the echo signals and being representative of the ability of the tissue to transmit elastic waves and of the homogeneity of the tissue with respect to the propagation of elastic waves.

摘要： An elastography device includes a probe with a single ultrasound transducer; or a plurality of ultrasound transducers, and a low frequency vibrator arranged to induce a displacement of said single ultrasound transducer or plurality of ultrasound transducers towards a tissue. The device is configured to emit a sequence of ultrasound pulses and to acquire echo signals received in response to track how elastic waves, induced by the displacement, travel in the tissue. The device is configured to generate, for one or more of the ultrasound pulses emitted a temporal offset upon emission, and/or a temporal offset upon reception, so that a difference thereof varies as a function of 2.d/Vus, where d is the displacement of the single transducer or plurality of ultrasound transducers, and where Vus is the speed of ultrasound in said tissue.
