In the medical applications of ultrasonic imaging, sound waves of high frequency are usually employed to produce in-depth cross-sectional images of internal organs. Special multi-element transducers ...

In a recently published study in the journal EPSL neuroelectronics, researchers from The Pennsylvania State University and Washington University in St. Louis have introduced a modular 16-channel ...

There have been important technological advancements made in the nondestructive testing (NDT) industry with total focusing method (TFM) capable inspection devices becoming more common. In terms of ...

Ultrasound is a mechanical pressure wave with a frequency above the range of human hearing (>20 kHz) that is increasingly used as a diagnostic, surgical, neuromodulation and drug delivery tool ...

A new system, developed by Tohoku University researchers in Japan in collaboration with Los Alamos National Laboratory in the US, takes 3-D images that can detect defects in metallic structures. The ...

Detecting objects underwater isn’t an easy challenge, especially when things get murky and dark. Radio waves don’t propagate well, so most techniques rely on sound. Sonar is itself farily simple, ...

Three-dimensional printed acoustic lenses that focus ultrasound beams to arbitrary shapes within the brain have been developed by researchers at the Technical University of Valencia. The lenses ...

Engineers at the University of California San Diego developed a soft and stretchy ultrasound patch that can be worn on the skin to monitor blood flow through major arteries and veins deep inside a ...

A two-in-one technology provides 3D images of structural defects, such as those that can develop in aircraft and power plants. A new system, developed by Tohoku University researchers in Japan in ...
