Researchers from North Carolina State University have developed a technique that allows ultrasound to penetrate bone or metal, using customized structures that offset the distortion usually caused by so-called ‘aberrating layers’.  The study is published in the journal Physical Review X. The team designed complementary metamaterials that will make it easier for medical professionals to use ultrasound for diagnostic or therapeutic applications, such as monitoring … Continue reading New technique enables ultrasound to penetrate bone, metal.
