Aesthetic Plastic Surgery, 1992
The author describes a revolutionary body contouring technique based on the surgical use of ultrasonic energy. It allows the selective destruction of only excess adipose tissue. The technique is based on three fundamental steps: (1) preparation of the areas to be treated with a large infiltration of a special solution, (2) treatment of the areas with ...

Electronics and Power, 1963
Ultrasonics has been used in medicine for about a decade. Progress in the subject is reviewed and discussed, particular stress being laid on physical aspects. The physics of ultrasonic fields, and their production and measurement, are briefly described. The main part of the review gives a critical description of the use of high intensity ultrasound for

The Journal of Prosthetic Dentistry, 1956
PPROXIMATELY ONE HUNDRED YEARS ago, it was learned that certain crystal A elements contracted in a magnetic field. Shortly thereafter a similar property was discovered in certain metals which, if rod-shaped, contracted in the direction of their long axes.

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2009
A detailed review is given of the application of high-frequency ultrasound (HFUS) at frequencies of 20 MHz and above for high-resolution, cross-sectional imaging of biological soft tissue. The state of the art of HFUS imaging systems is discussed with respect to the underlying engineering concepts, system designs, and available transducer technology ...

Retreatodontics and ultrasonics
Journal of Endodontics, 1988Retreatment of endodontically failing teeth is commonin most endodontic practices today. Two case reports are presented in which ultrasonics was used for retreatment. It is suggested that ultrasound can ease and, to some extent, simplify retreatment of some endodontic failures.

Molecular Biology, 2018
Ligand binding influences the dynamics of the DNA helix in both the binding site and adjacent regions. This, in particular, is reflected in the changing pattern of cleavage of complexes under the action of ultrasound. The specificity of ultrasound-induced cleavage of the DNA sugar-phosphate backbone was studied in actinomycin D (AMD) complexes with ...

Surgical Endoscopy, 1994
Following its development for cataract surgery, and gaining widespread use in neurosurgery and liver resection, ultrasonic dissection has been adapted for laparoscopic use. The turbulence, heat, and pressure generated by imploding bubbles disrupts tissues high in water content.
