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).
