The present invention relates to a system for the controlled fragmentation of solids by means of acoustic beams, comprising at least one acoustic beam generation unit (); and one feedback and control unit () of said generation unit (). Advantageously, the acoustic beams generated by the system are acoustic vortex beams; and the feedback and control unit () further comprises a feedback subsystem (), configured to receive the information relating to the fragmented solids and to utilize it so as to adapt the operation of the acoustic beam generation unit (). Given that the generation of shearing stresses is more efficient using vortex beams, the amplitudes of the ultrasonic field needed to fragment the calculi are much lower than in current extracorporeal shock wave lithotripsy techniques. Likewise, the system minimizes unwanted effects on soft tissues surrounding the solid.

The present invention relates to a method for obtaining elastic properties of a soft solid by means of quasi-omnidirectional transverse waves generated by a focused ultrasound beam, with a helical phase profile that produces an acoustic vortex that generates a transverse wave front, not only in the direction perpendicular to the ultrasound beam but also in the same direction as the ultrasound beam. The invention also allows control of the transverse wave front generated, which facilitates the carrying out of elastography studies at different frequencies and increases the amplitude of the transverse waves produced, thereby improving the signal-to-noise ratio.
