  • Acoustic lens for micromachined ultrasound transducers
    Patent number: 10770058
    Abstract: Matching layers configured for use with ultrasound transducers are disclosed herein. In one embodiment, a transducer stack can include a capacitive micromachined ultrasound transducer (CMUT), an acoustic lens, and a matching layer therebetween. The matching layer can be made from a compliant material (e.g. an elastomer and/or an liquid) and configured for use with CMUTs. The matching layer can include a bottom surface overlying a top surface of the transducer and a top surface underlying a bottom surface of the lens.
    Type: Grant
    Filed: May 31, 2018
    Date of Patent: September 8, 2020
    Assignee: FUJIFILM SONOSITE, INC.
