External ultrasound therapy of calcific aortic stenosis — First-in-man

Prospective, single-arm clinical investigation for the safety and feasibility study of Valvosoft Non-Invasive Ultrasound Therapy (NIUT) in patients with severe symptomatic aortic valve stenosis Cardiawave (France) has developed a Non-Invasive Ultrasound Therapy (NIUT) for the treatment of cardio-valvular diseases such as aortic stenosis. This is the primary valve disease in adults and one of the...

Hot ring produces microwave-powered ultrasound pulses wirelessly

Innovative wireless split-ring resonator concentrates microwaves into a hot-spot for ultrasound emission SPIE–INTERNATIONAL SOCIETY FOR OPTICS AND PHOTONICS Ultrasound imaging is one of the workhorses in a modern hospital. It hits the trifecta of being relatively cheap, portable, and non-invasive. The ability to cause future parents to get a bit emotional over fetus images is...

Rice team makes tiny, magnetically powered neural stimulator

by Rice University A sample of Rice University’s ‘magnetoelectric’ film atop a bed of uncooked rice. Rice neuroengineers created the bi-layered film to power implantable neural stimulators that are approximately the size of a grain of rice. The film converts energy from a magnetic field directly into an electrical voltage, eliminating the need for a...

Intelligent lung ultrasound provides crucial support for COVID-19 testing within minutes

by Hilde De Laat, Eindhoven University of Technology Establishing whether a patient is suffering from severe lung disease, possibly COVID-19, within a few minutes is possible using fairly simple ultrasound machines that are enhanced with artificial intelligence. A research team at Eindhoven University of Technology (TU/e) and the University of Trento in Italy has been...

Scientists develop noninvasive ultrasound neuromodulation technique

by Li Yuan, Chinese Academy of Sciences Epilepsy is a central nervous system disorder characterized by recurrent seizures resulting from excessive excitation or inadequate inhibition of neurons. Ultrasound stimulation has recently emerged as a noninvasive method for modulating brain activity; however, its range and effectiveness for different neurological disorders, such as Parkinson Disease, Epilepsy and...

Ultrasound solves an important clinical problem in diagnosing arrhythmia

Columbia Engineers used their electromechanical wave imaging technique to localize cardiac arrhythmias more accurately than 12-lead electrocardiograms alone, while providing 3D visualization for easier anatomical location of the arrhythmia source COLUMBIA UNIVERSITY SCHOOL OF ENGINEERING AND APPLIED SCIENCE New York, NY–March 25, 2020–Cardiac arrhythmias are a major cause of morbidity and mortality worldwide. Currently, the...

Ultrasound can temporarily increase mood, study suggests

Researchers find that targeting specific regions of the brain with ultrasound may increase a person’s mood. Could ultrasound, one day, be used to boost mood? A study recently published in the journal Frontiers in Human Neuroscience suggests that targeting a region of the prefrontal cortex with transcranial focused ultrasound (tFUS) — a new ultrasound technique...

Ultrasound Can Selectively Kill Cancer Cells

A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. Ultrasound waves—sound waves with frequencies higher than humans can hear—have been used as a cancer treatment before, albeit in a broad-brush approach: high-intensity bursts of ultrasound can...

Ultrasound destroys 80 percent of prostate cancers in one-year study

By Nick Lavars Treating prostate cancer through traditional means such as surgery or radiotherapy carries certain risks, with some patients experiencing impotence, urinary problems and bowel trouble, among other unwanted side effects. Safer and less invasive treatment options could soon be on the table, however, including a novel MRI-guided ultrasound technique that eliminated significant cancers in...
