More Information
Summary:A hybrid elastography method includes application of a continuous low frequency vibration and generation, using an ultrasonic transducer in contact with the viscoelastic medium, of a first series of ultrasonic acquisitions, the first series of ultrasonic acquisitions including groups of ultrasonic acquisitions, the groups of ultrasonic acquisitions being generated with a first repetition rate, each group of ultrasonic acquisitions including at least one acquisition, the continuous vibration generating an elastic wave within the viscoelastic medium; application of a low frequency pulse and generation, using the ultrasonic transducer, of a second series of ultrasonic acquisitions, the ultrasonic acquisitions composing the second series being generated with a second repetition rate, the low frequency pulse generating a transient shear wave propagating within the viscoelastic medium; the continuous vibration applied by the first vibrator being stopped before the application of the low frequency pulse.
