    摘要： An ultrasonic transducer assembly (10) for diagnostic imaging is provided. The ultrasonic transducer includes an elongated housing (12) that is configured and dimensioned to accommodate applicable anatomical constraints. The assembly includes a sensor assembly (20) that includes a two-dimensional matrix array of transducer elements (22) and a translation mechanism (32) to physically translate the two-dimensional matrix array of transducer elements (22) through a field of view of approximately 140 degrees by 80 degrees. An articulation control mechanism (38) allows a clinician to move the tip (14) of the ultrasonic transducer (10) into a desired imaging position, e.g., for fetal imaging.

    摘要： A digital multiline beamformer is provided which produces multiple receive beams in response to a single transmit event. An embodiment of the present invention includes a bulk delay which provides a common steering delay applicable to all of the beams received at one time. The bulk delay is succeeded by parallel filter processing paths which produce finely focused multiple beams simultaneously. In one embodiment a multiphase filter produces the samples for multiple beams, which is advantageous when the number of simultaneously produced beams is greater than the number of phases produced by the fine focus filter.

    摘要： An ultrasonic 2D array has elements extending in two dimensions which can be individually controlled and operated to form a 2D array for scanning a volumetric region in three dimensions. Individual ones of the elements can also be selected and operated together to form a 1D array for scanning a planar region in two dimensions. The array transmits scanlines to scan the volumetric region and the planar region in a time interleaved manner with the frame rate of the planar region be higher than that of the volumetric region. A spectral display may also be produced of a sample volume located in the planar region.

    摘要： An ultrasonic diagnostic imaging system processes echo information signals by means of a dynamic range map for displayed signals which is varied automatically throughout the image to control the displayed dynamic range and noise rejection level in regions of the image. In a preferred embodiment the displayed dynamic range and noise rejection level varied with both the range (depth) and lateral (scanline to scanline) dimensions of an ultrasonic image.

    摘要： An ultrasonic diagnostic system is provided which automatically sets up the TGC characteristic to be used for a given ultrasound examination. Upon user selection of a particular ultrasound application, a setup controller accesses a predetermined TGC characteristic for the selected application. The predetermined TGC characteristic is used to control the gain of a TGC amplifier and is also displayed to the user. By adjustment of a series of TGC controls the user can vary the TGC characteristic from the predetermined characteristic.
