Ultrasound device can see through concrete
If British scientists have their way, ultrasound, the same technology used by doctors to monitor fetuses, may soon be used to uncover construction defects — and maybe even find Jimmy Hoffa. Using technology developed by Cambridge Ultrasonics, technicians from UK firm Sonatest are able to hook up transducers to concrete structures and generate 3D images of their interiors. The data can be analyzed to find corrosion and other signs of structural damage. The equipment has also attracted the interest of police, who see the potential for tracking down bodies that might be embedded in the concrete. "If you scanned the area, you could find the void, but whether it would look like a big hole or would be person-shaped is anyone's guess," Wayne Woodhead, Sonatest managing director, told BBC News. Law enforcement officials, however, remain interested. Let's get one of these over to the Meadowlands and see what we find.
