The invention relates to an instrument for measuring the elasticity of a human or animal organ located behind the ribs. The instrument includes a casing having an actuator therein, the end of which is equipped with a transducer that is actuated in order to measure the elasticity of the organ. The measuring instrument also includes a mechanism for centering the transducer between the ribs.

Instrument for measuring organ elasticity, of the type comprising a centring means

A device for measuring elasticity of a human or animal organ or viscoelastic media having an ultrasonic signal after ultrasonic illumination including at least one sensor including an ultrasonic transducer, at least one position sensor, an actuator to trigger the device connected by wire link to an electric power source, and a controlled electrodynamic actuator attached to the ultrasonic transducer that generates a transitory low-frequency impulse having a frequency range between about 1 Hz and about 5000 Hz.

Device and method for measuring the elasticity of a human or animal organ

A device for measuring elasticity of a human or animal organ, or viscoelastic environments presenting an ultrasonic signal after ultrasonic illumination and consecutively establishing a representation in two or three dimensions of the elasticity, including at least one ultrasonic bar including a plurality of transducers, an excitor that generates and delivers a low-frequency, direct or indirect applied force, a receiver that acquires ultrasonic signals, a controller that commands and processes data, and a scanner that carries out scanning with the bar in one dimension (1D) or in two dimensions (2D) in two perpendicular directions, respectively, to obtain a representation of the measure of the elasticity in two (2D) or three dimensions (3D).
