All conventional digital receive beamformers provide dynamic receive focusing through delay profiles that vary dynamically tracking the depth from which the echo is received. But the transmit focusing has been static, and it has been limited to a single or a couple of discrete focal depths for decades. With the introduction of INFocus, dynamic receive focusing is complemented by dynamic transmit focusing which completes the round-trip dynamic focusing throughout the image. This improves detail resolution, contrast resolution, SNR and frame/volume rate.
INFocus is similar to synthetic aperture imaging in that information from different parts of the transmit aperture are contributed by separate pulse-echo events. This set of information is combined in a phase-sensitive, i.e., coherent manner, retrospectively after the receive beamformation. There are however three differences between INFocus and conventional synthetic aperture. First the component acquisitions use full transmit and receive apertures as opposed to single element or small apertures. Secondly the data is combined in a depth dependent manner that provides transmit focus at all depths. And lastly a progressive acquisition scheme is used so that frame rate is preserved and even improved, not reduced.
This capability is enabled on the SC2000 by a digital receive beamformer that has massive parallel beamformation capability and a Coherent Imageformer that has proprietary architecture and super processing bandwidth.
