Focused Ultrasound for Pediatric Diseases
Pediatrics, 2022Focused ultrasound (FUS) is a noninvasive therapeutic technology with multiple pediatric clinical applications. The ability of focused ultrasound to target tissues deep in the body without exposing children to the morbidities associated with conventional surgery, interventional procedures, or radiation offers significant advantages.

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.

Focused cardiac ultrasound in pregnancy
Journal of Investigative Medicine, 2023Cardiac disease in pregnancy is an important cause of maternal morbidity and mortality. In many high-income countries, acquired cardiac disease is now the largest cause of maternal mortality. Given its prevalence in low- and middle-income countries (LMICs), rheumatic heart disease is the most common cause of cardiac disease in pregnancy worldwide and ...

Focused Ultrasound for Chronic Pain
Neurosurgery Clinics of North America, 2022Chronic pain affects millions of Americans and is one of the leading reasons for individuals to seek medical attention. Focused ultrasound has been studied as a noninvasive treatment option for various pain disorders. Current studies have used focused ultrasound for ablation, neuromodulation, and opening of the blood-brain barrier for drug and therapy ...

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 ...

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.

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 ...

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.

Treating the Brain With Focused Ultrasound
IEEE Pulse, 2023Focused ultrasound is an early stage, noninvasive therapy with the potential to treat a range of medical conditions. Like diagnostic ultrasound, it uses sound waves above the range of human hearing. But its purpose is to interact with tissues in the body, rather than just produce images of them.
