Biological Effects of Acoustic Cavitation,exposures of this kind have caused clear effects, the mechanism of action appears to be related to the phenomenon of cavitation. It now remains to determine whether these observations have relevance for medical practice.

Effects on Soft Tissues with Special Reference to the Central Nervous System, accepted as a routine clinical procedure, it still resulted in the generation of a large body of reliable experimental data on the effects of high intensity ultrasound first on the mammalian brain and later on other soft tissues.

Exposure to Medical Ultrasound: Studies of Human Effects,ed States examined by diagnostic ultrasound range from 15–40% (NIH, 1984); in some countries, diagnostic ultrasound is a recommended routine prenatal procedure (NIH, 1984). The rapid development and expansion in the use of diagnostic ultrasound has been largely due to the perceived safety and medical benefits of this technology .

Interaction Mechanisms: Heating,the density and velocity of sound, respectively, for the medium; p is the acoustic pressure (total instantaneous pressure less the mean value) and <p.> denotes the time average of p.. If the ultrasound source is driven at frequency f, and if the approximations of linear acoustics hold, the pressure at any point will be given by
