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 ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently evolved into a formidable mechanism for wave manipulation. This assertion ...

Diagnostic ultrasound has become an invaluable imaging modality to healthcare professionals for the purpose of non-invasive examination of soft tissue, as it carries with it no associated risks 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 ...

Classification Society ClassNK has released its “Guidelines for Non-destructive Inspection by Phased Array Ultrasonic Testing”. Phased array ultrasonic testing is an advanced non-destructive ...

Levitation may seem like magic. However, for certain objects, and in certain conditions, it’s actually a solved technology. If you want to move small particles around or do experiments with ultrasonic ...

The autoclave has long defined thermoset composites processing — snap-cure epoxy prepreg systems are built around the premise that it doesn't have to.

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, ...
