Nintendo Wii-inspired $10 Microchip turns 2D ultrasound machines into 3D imaging devices

Researchers from Duke University and Stanford University have used a $10 microchip to make a simple 3D ultrasound imaging device that produces 3D scans similar in quality to CT or MRI scans. The 3D printed device works like a Nintendo Wii controller, by working out its orientation at a given point.
