A sneak peek at next-generation ultrasound imaging

The use of sound waves for non-invasively visualizing a fetus in the womb, via ultrasound imaging, is widely recognized. By emitting high-frequency sound waves into the body and converting their echo into electrical signals, real-time images can be constructed. Apart from medical imaging, these sound waves find application in biometric identification and gesture recognition in automotive and virtual-reality applications and various other fields.
