Tiny, wireless, injectable chips use ultrasound to monitor body processes
COLUMBIA UNIVERSITY SCHOOL OF ENGINEERING AND APPLIED SCIENCE IMAGE: Chips shown in the tip of a hypodermic needle. Columbia Engineers develop the smallest single-chip system that is a complete functioning electronic circuit; implantable chips visible only in a microscope point the way to developing chips that can be injected into the body with a hypodermic...

Ultrasound may have potential for treating pain after chemotherapy
Therapeutic ultrasound was a tool in Janice Yurick’s treatment arsenal for 15 years. Yurick, a now-retired physical therapist and former manager of supportive care services at the Cross Cancer Institute, had more than two decades of experience in oncology rehabilitation. She used the technology with patients and saw results, despite no actual studies to prove...

Ultrasound has potential to damage coronaviruses
Simulations show ultrasound waves at medical imaging frequencies can cause the virus’ shell and spikes to collapse and rupture. The coronavirus’ structure is an all-too-familiar image, with its densely packed surface receptors resembling a thorny crown. These spike-like proteins latch onto healthy cells and trigger the invasion of viral RNA. While the virus’ geometry and...

NEW ROLE FOR ULTRASOUND: IMAGING LUNGS
Advances in technique and technology have made ultrasound increasingly valuable for imaging a wide variety of medical applications, including pulmonary disease. That’s remarkable, in part, because it was once thought that ultrasound, which most people associate with pregnant mothers and prenatal check-ups, would never be useful in assessing lung health. And it’s important because it can improve...

3D ultrasound enables accurate, noninvasive measurements of blood flow
OAK BROOK, Ill. – A 3D ultrasound system provides an effective, noninvasive way to estimate blood flow that retains its accuracy across different equipment, operators and facilities, according to a study published in the journal Radiology. Measures of blood flow are important in helping clinicians determine how much oxygen and nutrient-carrying blood is reaching organs...
