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 ...

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 ...

Beamforming is a common signal processing technique used to create directional or spatial selectivity of signals sent to or received from an array of sensors or antennae. These arrays can be found in ...

A device that can perform 3D ultrasound imaging with just one large piezoelectric ultrasound transmitter and receiver has been developed by researchers in the Netherlands. Most ultrasound imagers use ...
