The first part of this paper reports an experimental investigation of some parameters that
control the occurrence of biologically effective cavitation‐type phenomena in the frequency …

Over the last decade, the main thrust of research on bio-effects of ultrasound has been
directed towards prevention of the occurrence of any effects that may potentially be injurious …

This overview of bioeffects of ultrasound presents some key aspects of selected papers
dealing with biophysical end-points. Its purpose is to establish a basis for exposure and …

It is proposed that the ultrasound frequency spectrum should be divided into three bands in
order to facilitate a more rational assessment of its health effects. Whilst statement of the …

Previous research leads to the conclusion that intense, noncavitating ultrasound affects
tissue at the level of macromolecular structures. As an initial study of the interaction of …

Gassy and degassed aqueous solutions of DNA were treated ultrasonically while monitoring
the field for dis-crete cavitation events. At irradiation intensities greater than about 500 …

The history of ultrasound related to bioeffects studies begins in the 1920's and continues to
the present. Because of the type of effects exhibited between high-frequency mechanical …

The phenomenon of thermal lesion production in tissues by unfocused ultrasound has been
modeled under the assumptions (1) that damage to the tissues is the result of a chemical …

The ultrasonic intensity threshold for producing lesions in mammalian brain tissue is not a
strong function of frequency (over the range of 1–10 MHz) for exposures longer than 1 sec. A …

Recent theoretical calculations have shown that small ultrasonically generated cavitation. A
single bubble has gas nuclei in water exposed to microsecond ultrasonic pulses above an …
