High-intensity focused ultrasound
2012Focal 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, 2006The 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 ...

Focusing ultrasound in biological media
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1989The 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.

Focused ultrasound training for clinicians
Critical Care Medicine, 2007Clinician use of diagnostic ultrasound, particularly at point of care and in emergency situations, is well established. The standard of training courses and of postcourse supervision and accreditation is variable, and international standards are required to maintain safety, accuracy, and credibility of the technique.

Focused Ultrasound for Neurodegenerative Diseases
Magnetic Resonance Imaging Clinics of North AmericaNeurodegenerative diseases are a leading cause of death and disability and pose a looming global public health crisis. Despite progress in understanding biological and molecular factors associated with these disorders and their progression, effective disease modifying treatments are presently limited. Focused ultrasound (FUS) is an emerging therapeutic

High-Intensity Focused Ultrasound
Gastrointestinal Endoscopy Clinics of North America, 1994High-intensity focused ultrasound (HIFU) is a technology that permits the use of ultrasound waves used for imaging and then focuses them as one would use a magnifying glass to focus sunlight. The ultrasound energy is absorbed by tissue and converted to heat and can be used to ablate tissue.

Neuroradiology: Focused Ultrasound in Neurosurgery
Ultrasound(US) is a longitudinal mechanical wave characterized by a frequency higher than 20,000 Hz. US generation is possible because of the discovery of the piezoelectric effect by the Curie brothers in 1880 and the inverse effect by Gabriel Lippmann one year later.Del Bene M. +3 more
