  • Ultrasonic probe
    Patent number: 7400079
    Abstract: An ultrasonic probe includes an ultrasonic transducer which is formed by sequentially laminating an acoustic lens, an acoustic matching layer, a piezoelectric element, and a backing member. The backing member arranged on a surface opposed side of the acoustic matching layer and the acoustic lens arranged to the piezoelectric element contains a synthetic rubber containing a mixture including acrylonitrile-butadiene rubber (NBR), ethylen-propylene terpolymer (EPDM), and at least inorganic fine powders.
    Type: Grant
    Filed: December 16, 2003
    Date of Patent: July 15, 2008
    Assignees: Olympus Corporation, GSK Corporation
    Inventors: Masayoshi Omura, Tohru Mizuguchi, Koumei Hatano
  • Ultrasonic transducer and method of manufacturing the same
    Patent number: 6995501
    Abstract: Materials having different compositions are arranged to prepare a molded form in which the sound velocity characteristic is varied from high frequency to low frequency from the center toward the periphery. An ultrasonic wave-radiating face of the molded form and the back face of the ultrasonic wave-radiating face are arranged in parallel to each other to prepare a transducer in which the center region can transmit/receive high-frequency ultrasonic waves and the periphery region can transmit/receive low-frequency ultrasonic waves.
