Patent ID: 8241216

Claim:
In a non-transitory computer readable storage medium having stored therein data representing instructions executable by a programmed processor for retrospective dynamic transmit beamformation in medical ultrasound imaging, the storage medium comprising instructions for: acquiring data from multiple pulse-echo acquisition events, each pulse-echo acquisition event of the multiple pulse-echo acquisition events corresponding to different transmit delay profiles; aligning the data with offsets, the offsets corresponding to a temporal shift in one of the transmit delay profiles to a tangential intersection with receive wavefronts for the data; combining the data as aligned by the aligning; and generating an image as a function of combined data resulting from the combining; wherein one of the transmit delay profiles corresponds to temporal evolution of a spherical or cylindrical transmit wavefront to achieve the tangential intersection with one of the receive wavefronts corresponding to a receive focus from an initial time when the receive focus is formed.
