The sound propagates through many layers of tissue.
Because of the focal gain, only tissue at the focus is destroyed. This section needs more medical references for verification or relies too heavily on primary sources.

Title: power ultrasonics applications high intensity ultrasound. The ultrasonic transducers convert electrical or mechanical energy to sound energy. The acoustic higher vapour pressure. Cavitation bubbles form pressure is a sinusoidal wave dependent on time less easily in a highly viscous environment.
At low intensity [11] The ultrasonic waves cannot travel through amplitude , the pressure wave induces motion vacuum and can travel with the speed of sound and mixing within the fluid, so called acoustic in a given medium. Their velocity remains streaming [12]. At higher intensities, the local constant in homogeneous media.
The gels were obtained [19]. The use of a powerful ultrasonic waves are reflected and refracted just ultrasonic transducer, directly fixed above a like light waves. It may be due to a partial vacuum on the media. Ultrasound travels through various media foam bubble surface [20]. The speed of sound 6. Sound is likely to travel faster through solids, followed by Removal of the air in the solution is possible by liquids and gases.
Reduction of pressure and boiling are common degassing methods. The 6. Degassing with wider applications in almost all fields including ultrasound is applied to carbonated drinks, beer medical scanning ultrasonic therapy, mineral de-fobbing and wine [22]. The effectiveness of processing, nanotechnology, food and beverage degassing is reduced by the increase of the technology, non-destructive testing, industrial viscosity of the applied liquid medium [23].
Over the 6.
Ultrasound Studies to control biofilm formation by processing of fluid foods. Part two looks at applications of high power ultrasound in materials engineering and mechanical engineering, food processing technology, environmental monitoring and remediation and industrial and chemical processing including pharmaceuticals , medicine and biotechnology. During inertial cavitation, very high temperatures occur inside the bubbles, and the collapse is associated with a shock wave and jets that can mechanically damage tissue. On the contrary, the methods of traditional destructive can be applied only on a limited sample of fruit after harvesting [ 31 ]. Leonardo da Vinci.
McClements, [7] inactivation and cutting processes, assisted with reported the assist of ultrasound in cooking ultrasound are some of the most studied and provides better quality in cooked meats. By the help of nuclei formation and rapid cooling ability of ultrasound, the desired 6. The effectiveness of thermal processing depends on temperature and time. By the way, the 6.
The sanitary purpose of the properties of food products. Ultrasonic power of application has also a side effect on around W was found to be optimal for tenderization. Ultrasonic tenderization applied on maximum microbial inactivation [18].
It has been poultry meat, veal and beef. By products. Salt, commonly Fig. Sonication increases the transfer of salt and 6. Particle size is one of the main important parameters for the success and stability of both 6. In some cases, the existence of microparticles In literature ultrasound assisted drying is called avoids the need of addition of surfactants.
The acoustic drying and has potentially great existence of microparticles makes the emulsions commercial importance. Ultrasound creates more stable. In-line applications are possible in microscopic channels in the material and these production lines [32]. Fruit juices, mayonnaise channels allow the easy transportation of the and tomato ketchup, homogenization of milk [33] vapour from centre to surface. Gallego-Juarez, and aroma encapsulation are some of the [27] noted that heat transfer is increased applications in industry.
Sonication treatment permits the 6.
The ultrasonic knife is a blade attached through a Heat sensitive foods may be dried with the shaft to an ultrasonic source. Ultrasound ultrasound assisted drying applications to avoid improves the performance of food cutting or alterations of flavour, colour and nutritional slicing. Ultrasound provides the minimization of values. The treatment produced a reduction also waste and energy requirement [34]. The clogging is the main problem when cleaning procedure discussed.
Ultrasonic in filtration. By the time, the cake formation in energy is now used extensively in critical front of the surface of the filter resists the transfer cleaning applications to both speeds and of the material through the filter.
Ultrasound enhance the cleaning effect.
