Existing defect detection tools using ultrasound rely on phased array ultrasound. In this method, many transducers are pointed in the same direction to generate an image of that specific area. This ...

Advances in ultrasound—the same imaging technology that uses sound waves to allow doctors to monitor babies in utero—are being applied by engineers at the University of California San Diego to make ...

This talk will present the methodology of using the guided ultrasonic waves generated by the rodent to track its physiology, behavior, and psychological state. When behaving in an environment, muscle ...

This is a sound head created by John J. Wild in 1949. It is a brass capsule constructed by Wild to house a piezoelectric quartz crystal, or transducer. The crystal is still within the sound head. Wild ...
