Shock wave generator for generating focussed shock waves - has acoustic lens between pressure pulse source and reflector surface enabling rapid focus zone displacement

摘要

The shock wave generator contains a pressure pulse source (8), a reflector (9) and an acoustic propagation medium filling the space between the pressure pulse source and reflector. The pulses are reflected to coincide in a focus zone (F1,F2). At least one acoustic lens (18) placed between the pulse source and reflector surface is shaped to cause a displacement of the focus zone with respect to the pulse source. USE/ADVANTAGE - For generating focussed shock waves. Enables focus zone to be displaced rapidly and simply.
