Ultrasound

Researchers have developed a device that assesses ear infections using ultrasound.

A team of researchers has developed a non-invasive tool which not only detects circulating tumor cells in the bloodstream, but can blast them away at the same time. Dubbed the Cytophone, it employs a laser which heats the CTCs, subsequently detecting them via ultrasound.

​We're increasingly seeing 3D-printed metal components being used in fields such as aviation, where failures could be catastrophic. It's therefore very important to check those items for structural flaws before they're installed, and the best way of doing so may involve freezing them in ice.

An incredible new study suggests that low-intensity ultrasound can be used to target very specific brain regions and alter an animal's decision-making processes. The technique, demonstrated in macaques monkeys, prompts actual behavioral changes using non-invasive ultrasound waves.

The pigment melanin is a natural defense against skin cancer – and now it could help fight other cancers too. Researchers at the Technical University of Munich and Helmholtz Zentrum München have found that melanin-loaded nanoparticles can help diagnose tumors and slow their growth.

A promising new study is documenting the long-term effects of a novel surgical procedure using ultrasound to reduce blood pressure in patients with hypertension. The one-off procedure, called renal denervation, is hoped to offer patients an alternative option to taking hypertension drugs.

Ultrasound technology might be about to get a whole lot more powerful. Researchers have developed an “ultra” ultrasound sensor that is so sensitive it can hear air molecules moving around or the vibrations of individual cells.

A new technique using ultrasound to clear the toxic protein clumps thought to cause dementia and Alzheimer’s disease is moving to the first phase of human trials next year. The treatment has proven successful across animal tests and presents an exciting, drug-free way to potentially battle dementia.

Although wind turbines may be a valuable source of eco-friendly energy, they do have at least one drawback – bats are frequently killed by their spinning blades. A promising new system is designed to help keep that from happening, however, by producing an ultrasonic acoustic field.

New research from University College London suggests a quick ultrasound scan examining blood vessels in the neck may be able to effectively predict a person's risk of developing cognitive decline more than 10 years before symptoms appear.

Researchers at the University of Sussex have developed SoundBender, a technology that bends sound waves around obstacles to acoustically levitate objects above them.

​When someone has a head injury, it's vitally important to know if they're experiencing elevated intracranial pressure – it can cause damage to the brain and spinal cord if left unchecked. A newly-developed device could make the diagnosis process faster and easier than ever before.
