HIFU induced cavitation with reduced power threshold

摘要

The invention relates to high intensity focused ultrasound devices. Furthermore the invention relates to an apparatus for irradiating a liquid sample with acoustic energy to generate cavitation in the liquid sample. The apparatus (100) comprises a source and is adapted to receive a cartridge (105) in such a way, that the apparatus focuses the HIFU waves emitted from the source onto a liquid air interface that is present within the cartridge. This focusing is performed when the cartridge is inserted into a receiving section of the apparatus.
