Miniature ultrasound transducer

摘要

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 (301) and in electrical communication with the electronic circuitry (302). The diaphragm (304) has an arcuate shape, formed by applying a differential pressure, that is a section of a sphere. A binder material (314) is in physical communication with the diaphragm (304) and the substrate (300).
