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 invention relates to a method for producing a lens for an ultrasound apparatus, as well as to an apparatus comprising the lens. The method comprises choosing a source point, providing a treatment volume situated inside a bone tissue model, providing a plurality of nodes distributed inside the treatment volume, and simulating the emission of a spherical wave from each of the nodes. Thus, a simulated wave front is created, in which each spherical wave has an amplitude and a phase, there being at least two nodes with different amplitudes and/or phases. The simulated wave front is received on a receiving surface. On the basis of the processed results, a holographic lens surface is designed, which can generate a wave pattern equivalent to the simulated wave.
