Cardiovascular cavitation

Medical Engineering & Physics, 2009
This article reviews the role of cavitation in the therapeutic applications of ultrasound and laser surgery, and the cavitation effects in mechanical heart valves. Whenever laser pulses are used to ablate or disrupt tissue in a liquid environment, cavitation bubbles are produced which interact with the tissue. The interaction between cavitation bubbles

Cavitation and Cavitation Erosion

2014
In this chapter, an introduction to cavitation and cavitation erosion is presented. Cavitation involves the development of various types of vapor structures (such as attached cavities, travelling bubbles, vortical cavities, bubble clouds) in liquid flow due to a drop in the local pressure below a critical value usually close to the vapor pressure ...

Cavitation Bioeffects

Critical Reviews™ in Biomedical Engineering, 2006
Acoustic cavitation takes place when tiny gas bubbles oscillate, grow, and collapse in liquid under the influence of ultrasonic field. This study reviews cavitation bioeffects that are found both in vivo and in vitro when exposed to either low- or high-power acoustics.

Coccidioidal pulmonary cavitation

The American Journal of Medicine, 1958
Abstract 1.1. Seventy-seven cases of coccidioidal pulmonary cavitation have been summarized. 2.2. Cavitation is found in about 1 to 3 per cent of hospitalized patients with coccidioidomycosis, or about 0.1 per cent of all patients with this disease. 3.3.

Cavitation nuclei and cavitation noise

The Journal of the Acoustical Society of America, 1988
Present understanding of the influence of nuclei on the onset of cavitation and the generation of radiated cavitation noise is reviewed. It is now generally accepted that the formation of cavities in a liquid at only moderate negative pressures requires the presence of nuclei in the liquid; the experiments of Greenspan and Tschiegg, among others, leave
