Shock wave generator with reflector - has several reflector sections, each associated with different focus zone enabling rapid focus zone displacement

摘要

The shock wave generator contains a shock wave source (8), a reflector (9) and an acoustic propagation medium filling the space between the shock wave source and reflector. The shock waves are reflected to coincide in a focus zone (F1-F3). The reflector has several surface sections (21a-21c), each associated with a different focus zone. The shock wave source is operated so that the shock waves emanating from it are each incident on a single reflector surface section. USE/ADVANTAGE - for generating focussed shock waves. Enables focus zone to be displaced rapidly and simply w.r.t. source.
