Document Type and Number:
Japanese Patent JP6496749
Kind Code:
B2
Abstract:
Method for generating a shear wave in a target region of a soft solid, includes the following steps: a) generating at least two shear waves with a first and a second source of shear waves in the target region; b) detecting a propagation pattern of the shear wave in the target region with a detector unit including a row of ultrasonic transducers aligned on a first direction perpendicular to a detection direction of each or a single ultrasonic transducer movable along a first direction perpendicular to its detection direction; c) proceeding to a time reversal of the detected propagation pattern; and d) submitting the target region to an inverted excitation set of forces based on the temporally inverted propagation pattern. During step b), a first propagation pattern is detected when only the first source is active and a second propagation pattern is detected when only the second source is active.
