Mammalian tissues have differing sensitivities to damage by physical agents such as
ultrasound. This article evaluates the scientific data in terms of known physical mechanisms …

Ultrasound energy exerts important cellular, genetic, thermal, and mechanical effects.
Concern about the safety of ultrasound prompted several agencies to devise regulatory …

In the early summer of 1965, one of the present authors (MJE) noted an outbreak of
abortions and congenital malformations among a guinea pig colony in Cobbitty, NSW …

Methods of fixing and processing tissue and samples on a membrane by using ultrasound
radiation as a part of the method are presented. Ultrasound of a frequency in the range of …

Processes that can produce a biological effect with some degree of heating (ie, about 1° C
above the physiologic temperature) act via a thermal mechanism. Investigations with …

Ultrasonic cavitation bubble phenomena play a key role in numerous medical procedures
such as ultrasound-assisted lipoplasty, phacoemulsification, lithotripsy, brain tumor surgery …

Objective: To review the biological effects and safety of obstetric ultraSOund. Outcome:
Outline the circumstances in which safety may be a concern with obstetric ultrasound …

Tissues of the central nervous system are sensitive to damage by physical agents, such as
heat and ultrasound. Exposure to pulsed spectral Doppler ultrasound can significantly heat …

Ultrasound imaging of the brain is routinely used to monitor the development and resolution
of brain lesions among premature and compromised newborn human babies. However …

Temperature was measured in the brain in live near-term fetal guinea pigs (62–66 d
