Ultrasound

An emerging method is adapting x-ray to image soft tissue, so that its higher resolution can reveal tumors earlier than MRI or ultrasound. And now, researchers have taken the first image using the new x-ray method, as a proof of concept.

Ultrasound has become an indispensable tool for showing us internal tissues of the human body, but a new ultrasonic biosensor could see it offer a far more detailed and dynamic picture as the body responds to drugs or disease.

One consequence of cancer and other diseases spreading throughout the body can be the hardening of the extracellular matrix surrounding cells. Scientists have now developed a new way to non-destructively detect such changes using sound waves.

A team of researchers is proposing a radical new technique for killing cancer cells using low-intensity ultrasound waves. The work is still at an early stage but cell tests have shown sound waves can destroy cancer while leaving healthy cells intact.

The quality of 3D-printed metal parts could soon improve, thanks to new research out of Australia. Scientists there have determined that the application of ultrasound boosts the strength of such items, by modifying their microstructure.

Researchers from MIT have revealed the very first images of a human generated through a novel laser ultrasound imaging technique. Unlike conventional ultrasound, the new technique does not require any skin contact with the body.

A new type of ultrasound technology promises to make a touch-sensitive surface out of just about any common material – metal, glass, wood, plastic – which could open up a number of new ways to interact with our gadgets.

A new study from Northwestern University is demonstrating evidence a novel implantable ultrasound device allows a less toxic formulation of chemotherapy to cross the blood-brain barrier and destroy deadly tumors.

A safer and less invasive treatment option for prostate cancer could soon be on the table, with a novel MRI-guided ultrasound technique eliminating significant cancers in 80 percent of subjects in a year-long study.

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.
