Method and shock wave head for the generation of shock waves focused ultrasound -

摘要

A method for generating ultrasound - shock waves (2a, d) with a shock wave head (30), in which a shock wave source (32) is arranged, with the temporally successively in each case in a focus (fa – d) focused ultrasound - shock waves (2a, d) can be produced, whereby the ultrasound - shock waves are produced one after another along different, mutually parallel sound axes (za – d) and a spread the respective focus (fa – d) surrounding zone in which (8a – d) with a focal width (b), said foci (fa – d) at a distance from each other in predetermined positions are arranged in such a way that the focal volumes (8a – d) of temporally successive ultrasound - shock waves (2a, d) in the region of the working zones (8a – d) are superimposed in such a way that a cohesive useful load (20) is obtained, whose effective focal width (σ b) is greater than the focal width (b) of the working zones (8a – d) of the individual ultrasound - shock waves (2a – d).
