Abstract: In an ultrasound imaging system which produces synthetically transmit focused images, the multiline signals used to form image scanlines are analyzed for speed of sound variation, and a map 60 of this variation is generated. In a preferred implementation, the phase discrepancy of the received multilines caused by speed of sound variation in the medium is estimated in the angular spectrum domain for the receive angular spectrum. Once the phase is estimated for all locations in an image, the differential phase between two points at the same lateral location, but different depth, is computed. This differential phase is proportional to the local speed of sound between the two points. A color-coded two- or three-dimensional map 60 is produced from these speed of sound estimates and presented to the user.

The processor activates the array of acoustic elements to acquire ultrasound data using a sequence of transmit-receive pairs, generates a B-mode image using the acquired ultrasound data, forms a plurality of sub-apertures comprising a portion of the transmit-receive pairs, groups the sub-apertures into temporally-spaced ensembles, determines a flow estimate based on a comparison of at least one of sub-apertures within an ensemble, ensembles within an aperture, or different apertures, and outputs a graphical representation of the B-mode image and the flow estimate to a display.

Abstract: An ultrasound system according to the present disclosure may include a beamformer configured to perform per-channel weighting on the RF signals received at each channel in order to reduce noise clutter in the image. For this purpose, the beamformer may receive at one or more channels associated with an active aperture, sets of receive signals associated with respective transmit beams that at least partially overlap. The beamformer may alter the receive space, e.g., to align the sets of receive signals to a common location (e.g., between the transmit beams) and generate a coherence-based weighting value that may be indicative of blockage. The coherence-based weighting value may be applied on a per-channel basis to the receive signals. The beamformer may also communicate the coherence metric to the controller for altering the transmit space.
