Abstract: An ultrasound system produces high quality images at a high framerate of display. A plane or volume to be imaged is scanned by different diverging transmit beams to acquire a series of different sub-frames, the number of sub-frame acquisitions comprising a total number of transmit beams which would produce a high quality image. The echoes received in response to the transmit beams of a sub-frame are coherently combined with the echoes received in other sub-frames. Each time the echoes of a new sub-frame have been coherently combined with the echoes of all other different sub-frames, a full image is produced. After a complete series of sub-frames has been received and the echoes combined, another series of sub-frame acquisition is commenced and a new series of sub-frames acquired. As each new sub-frame is acquired, it is coherently combined with all the other different and most recently acquired sub-frames. This technique produces a new image at the sub-frame scanning rate, rather than awaiting a completely new series of sub-frames before forming a new image.

Abstract: Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system, comprising an array of acoustic elements configured to transmit ultrasound energy into an anatomy and to receive ultrasound echoes associated with the anatomy; and a processor circuit in communication with the array of acoustic elements and configured to receive, from the array, ultrasound channel data corresponding to the received ultrasound echoes; normalize the ultrasound channel data by applying a first scaling function to the ultrasound channel data; generate beamformed data by applying a predictive network to the normalized ultrasound channel data; de-normalize the beamformed data by applying a second scaling function to the beamformed data; generate an image of the anatomy from the beamformed data; and output, to a display in communication with the processor circuit, the image of the anatomy.

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.
