An elastography device comprising: a probe that comprises a protruding part to be applied against the body of a subject, a low frequency vibrator arranged to move the protruding part, at least one ultrasound emitter and one ultrasound receiver; and an electronic unit. The electronic unit is adapted to alternatively control the elastography device so that it operates (a) in a guidance mode to determine whether the probe is correctly positioned in front of a region of the body to be probed to carry out a measurement of a mechanical property of the probed region and (b) in a measurement. In the guidance mode, the vibrator delivers a plurality of successive probing pulses (PRB), each being a transient, low frequency mechanical pulse, and the electronic unit determines a propagation quality indicator (Q) representative of an aptitude of the probed region to transmit the probing pulse.

Elastography device and method

A device calculates a score reflecting a state of liver damage, the calculating device being designed to calculate a score using the following physical parameters: a parameter corresponding to inflammation and/or fibrosis; and a parameter corresponding to steatosis.

Non-invasive device for detecting liver damage

A non-invasive system for calculating a human or animal score, the system including a measurement slave device constructed and arranged to carry out measurements of biological parameters; a measure slave device constructed and arranged to carry out measurements of physical parameters; a master device constructed and arranged to collect the biological and physical parameters and calculate the human or animal score, the score including biological and physical parameters.

Non-invasive system for calculating a human or animal, reliable, standardized and complete score

A method for measuring at least one property of biological tissue, including: positioning an ultrasonic transducer opposite the biological tissue to be measured; generating an ultrasonic signal within the biological tissue; acquiring at least one ultrasonic signal reflected by the biological tissue; determining at least one parameter of the biological tissue using the acquisition of the ultrasonic signal reflected by the biological tissue, the at least one parameter being representative of the biological tissue; comparing the at least one parameter of the biological tissue with at least one reference parameter of a target biological tissue so as to confirm the hypothesis of the presence of the target biological tissue opposite the ultrasonic transducer; and determining at least one property of the biological tissue on the basis of the result of the comparison. The method can be directly used in the field of humans or animals.

Method for measuring at least one property of biological tissue

A method for determining, in real time, the probability that target biological tissue is opposite an ultrasonic transducer, the method including: transmitting, via an ultrasonic transducer, an ultrasonic signal into biological tissue; the ultrasonic transducer receiving the transmitted ultrasonic signal which has been backscattered by the biological tissue; calculating at least two instantaneous parameters of the backscattered ultrasonic signal; calculating a predictive value of the presence of an acoustic signature of target biological tissue, the predictive value being calculated via a statistical law using the at least two calculated instantaneous parameters; estimating the probability that the target biological tissue is opposite the ultrasonic transducer, the estimation depending on the calculated predictive value and/or on at least one strength condition based on at least one of the two calculated instantaneous parameters.
