    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.

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. An ultrasonic probe containing the inventive array can be quickly switched between two and three dimensional imaging modes to produce both a three dimensional image and a two dimensional image in real time.

    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: Multiline acquisition is used to acquire groups of beams in response to transmit pulses. At least some of the beams from spatially adjacent groups are coaxially aligned. The echo information is detected and coaxially aligned beams are blended together using weighting functions which vary as a function of the time and location of the blended beams from their transmit beam apertures to gradually blend the aligned beams together spatially, thereby reducing multiline image artifacts. Echoes from moving objects in coaxially aligned beams may be aligned axially before the beams are blended together.

    摘要: An ultrasonic diagnostic imaging system and method are provided for producing r.f. interpolated image lines with reduced susceptibility to motion artifacts. A multiline beamformer receives multiple scanlines in response to each transmitted beam. Image lines are produced by r.f. interpolation of these multiline scanlines in a temporally consistent manner. In an illustrated embodiment, each image line is produced by tle interpolation of scanlines produced in response to at least two transmitted beams. In a preferred embodiment the interpolated image lines are produced by a [1 2 1] lateral filter.
