Ultrasound able to penetrate bone, metal, with new technique

Researchers from have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by these so-called “aberrating layers.”

Using a new technique, “it’s as if the aberrating layer isn’t even there,” says researcher .
