1. A device for measuring elasticity of a human or animal organ or viscoelastic media having an ultrasonic signal after being subjected to ultrasonic impulses comprising:

  • at least one sensor comprising an ultrasonic transducer,at least one position sensor,an actuator to trigger the device connected by wire link to an electric power source,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 and results in a low-frequency vibration or stress that is controlled in time and amplitude and allows an operator to apply pressure to the organ, anda computer configured to calculate velocities of tissue deformations.
