Ultrasonic array scanning of the kidney
Ultrasound in Medicine & Biology, 1974Abstract An ultrasonic scanning system has been devised, utilizing an array of six plane transducers, each used as a separate transmitter-receiver. The transducers were arranged in a concave assembly so that their beams intersected at a point equidistant from each face.

Applied Acoustics, 2021
Abstract Ultrasonic array modelling is widely used to understand the performance of new transducer materials or geometries in a range of application scenarios. However, array modelling from first principles is both time-consuming and challenging due to the required knowledge of accurate acoustic and piezoelectric properties.

The Journal of the Acoustical Society of America, 1978
The subject of multielement ultrasonic transducers is presented, with emphasis on describing the ultrasonic transducer design techniques and time-delay pulsing schedules used to achieve real-time imaging, beam steering, and beam focusing. Transducer design techniques make use of a first-order scattering theory in fluids, which model quite nicely many ...

Ultrasonic transducers and arrays
IEEE Engineering in Medicine and Biology Magazine, 1996Ultrasonic imaging is one of the most important and still growing diagnostic tools in use today. To better understand transducer/array performance and some of the factors that prevent ultrasonic imagers from reaching higher resolution, this article reviews past achievements and current developments in the technology, including piezoelectric materials ...

Simulations of ultrasonic fields of radial ultrasonic array
Ultrasound, 2007Objective of this study was to develop an ultrasound probe small enough (diameter – less then 10mm, length less then 6mm) The probe must send and receive signals in 360 degrees, obtaining in this way the information needed for the software to generate a 2D image.
