  • Transmit beamforming in 3-dimensional ultrasound
    Patent number: 9182658
    Abstract: An ultrasound system comprises a probe including a two-dimensional (2D) array of transducer elements that form an aperture having a plurality of receive elements that are configured to receive ultrasound signals. The transducer elements form at least one transmit sub-aperture that is configured to be interconnected with a fixed group of the transducer elements within the aperture. Transmitters generate electrical transmit signals, and at least one transmit sub-aperture processor (tx SAP) maps the transducer elements within the fixed group of the transducer elements to the transmitters in a transmit configuration based on a beam steering direction.
    Type: Grant

    Date of Patent: November 10, 2015
    Assignee: General Electric Company
    Inventors: Kjell Kristoffersen, Bruno Hans Haider, Thomas Halvorsroed, Steinar Bjaerum
