摘要:
The present disclosure provides various embodiments of an ultrasound transducer for use in intravascular ultrasound (IVUS) imaging. An exemplary ultrasound transducer includes substrate having a first surface and a second surface opposite the first surface. A well is disposed in the substrate that extends from the first surface to the second surface, where a well surface of the substrate defines a shape of the well. The well surface has a greater surface area than a cylindrically-shaped well surface. The ultrasound transducer further includes an arcuate-shaped transducer membrane is positioned within the well adjacent to the first surface of the substrate, and a backing material is disposed in the well that physically contacts the well surface and the transducer membrane. The backing material secures the arcuate-shape of the transducer membrane.
