Ultrasound Transducers

Journal of Diagnostic Medical Sonography, 2015
Diagnostic medical ultrasound transducers have evolved through the years and have contributed significantly to improved patient care. This article discusses the history and types of transducers and the elements that have changed over time. There has been a sharp transition from natural to human-made elements and from one to many in a single transducer.

Ultrasound Transducers

2006
Abstract The history of transducer development for medical imaging and therapeutic applications is closely coupled with the invention of transduction mechanisms and the development of transducer materials. Six transduction mechanisms can be identified as originating in the 19th century: Electromagnetic: In the presence of a static or ...

Miniature ultrasound transducer

The Journal of the Acoustical Society of America, 2004
An ultrasonic transducer (108) for use in medical imaging comprises a substrate (300) having first and second surfaces. The substrate (300) includes an aperture (301) extending from the first surface to the second surface. Electronic circuitry (302) is located on the first surface. A diaphragm (304) is positioned at least partially within the aperture (
