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 ...

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 ...

Journal of Neural Engineering, 2016
Ultrasonic waves can be non-invasively steered and focused into mm-scale regions across the human body and brain, and their application in generating controlled artificial modulation of neuronal activity could therefore potentially have profound implications for neural science and engineering.

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.

Ultrasonic probe, ultrasonic imaging apparatus and ultrasonic imaging method
The Journal of the Acoustical Society of America, 2007An ultrasonic probe is disclosed for reducing the influence of electromagnetic wave leakage to a magnetic resonance imaging (MRI) device even when the probe is inside the MRI gantry. The ultrasonic probe includes a piezoelectric material, an acoustic matching layer provided on the ultrasonic radiation side of the piezoelectric material, and backing ...
