Abstract
A method and apparatus for electronic volume data acquisition using ultrasound generates image data in a scanning and imaging process known as coherent aperture combining beamforming (CAC-BF). The CAC-BF technique can be applied in an azimuth dimension and/or an elevation dimension, to form an ultrasound image line, image plane, or image data cube. Several innovations relating to the design and ordering of shots and efficient weighting algorithms that address various performance issues associated with B-mode and other modes such as Doppler, and harmonic imaging are disclosed. The invention has significant advantages over other synthetic aperture imaging techniques and conventional imaging techniques by supporting higher resolution, larger volumes and/or shorter acquisition times than comparative techniques, using similar system hardware complexity.
