Wilbur A. Reckwerdt has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method and apparatus for performing imaging
    Patent number: 5379642
    Abstract: An ultrasound imaging system for performing dynamic focusing of ultrasonic waves during transmit and receive. The present invention includes a method and a means for transmitting ultrasonic waves to a multiple depths within a body. The present invention optimizes the transmit frequency for each of the multiple depths to localize the energy of the ultrasonic waves. The present invention also includes a method and means for performing dynamic receive focusing of the reflected ultrasonic waves produced by discontinuities in the body, such that it is focused to receive ultrasonic waves from the depth at which the transmitted ultrasonic waves are focused.
    Type: Grant
    Filed: July 19, 1993
    Date of Patent: January 10, 1995
    Assignee: Diasonics Ultrasound, Inc.
    Inventors: Wilbur A. Reckwerdt, Sved O. Ishrak, Wanqun Bao
