Title: TWO DIMENSIONAL ULTRASONIC ARRAY TRANSDUCER WITH ONE DIMENSIONAL PATCHES
Abstract:
A diagnostic ultrasound system has a 2D array transducer which is operated with 1xN patches, patches which are only a single element wide. The "N" length of the patches extends in the elevation direction of a scanned 2D image plane, with the single element width extending in the lateral (azimuth) direction. Focusing is done along each patch in the elevation direction by a microbeamformer, and focusing in the lateral (azimuth) direction is done by the system beamformer. The minimal width of each patch in the azimuth direction enables the production of images highly resolved in the azimuthal plane of a 2D image, including the reception of highly resolved multilines for high frame rate imaging.
