There is, however, a lack of understanding of HIFU generated cavitation activity in tissue. ...
Passive and active cavitation detection techniques have been combined to give a system for use in HIFU fields. ...
Another hypothesis investigated was that non-linear propagation of the HIFU field generated superharmonics that were absorbed more readily in the tissue. ...
