Focused ultrasound: focused on tremor

Expert Review of Medical Devices
Magnetic resonance-guided focused ultrasound (MRgFUS) has emerged as a leading noninvasive therapy for tremor, offering a precise, lesion-based alternative to deep brain stimulation (DBS) and traditional lesioning techniques. By using phased ultrasound arrays to focus energy at intracranial targets, MRgFUS allows for real-time visualization and ...

Focused Ultrasound and Lithotripsy

2016
Shock wave lithotripsy has generally been a first choice for kidney stone removal. The shock wave lithotripter uses an order of microsecond pulse durations and up to a 100 MPa pressure spike triggered at approximately 0.5-2 Hz to fragment kidney stones through mechanical mechanisms. One important mechanism is cavitation. We proposed an alternative type

High-intensity focused ultrasound

2012
Focal therapy (FT) is an emerging noncancerous tissue preservation strategy that aims for treating only the areas of cancer. FT has attracted attention over the several years in the field of treatment of localized prostate cancer. On the other hand, the use of minimally invasive ablative techniques in the management of patients with low-grade and ...

Transcranial Focused Ultrasound Surgery

Topics in Magnetic Resonance Imaging, 2006
The development of high-intensity ultrasound technology into a system for performing image-guided noninvasive ultrasound neurosurgery has developed at a relatively rapid pace in the past few years. Magnetic resonance imaging has contributed significantly to this development by providing a modality by which percutaneous ultrasound treatments can be ...

Peripheral Focused Ultrasound Neuromodulation (pFUS)

Journal of Neuroscience Methods, 2020
A fundamental limit to the study of the peripheral nervous system and its effect on organ function is the lack of tools to selectively target and stimulate specific neurons. Traditional implant and electrode-based systems remain too large and invasive for use at the organ or sub-organ level (without stimulating or effecting neighboring organs and ...

MR-Guided Focused Ultrasound Surgery

Journal of Computer Assisted Tomography, 1992
Magnetic resonance guided focused ultrasound surgery provides a minimally invasive controlled method for selectively destroying deep-lying tissue. A thermal analysis of focused ultrasound provides an estimate of the time-dependent temperature distribution and thermal dose required for ultrasound surgery.

Focusing ultrasound in biological media

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1989
The authors present a formulation for calculating the field distributions for an ultrasonic imaging system when focusing in biological media. A biological medium is characterized in terms of its complex and frequency-dependent compressibility that, in turn, depends on the medium relaxation time and specific heat ratio.
