摘要： An echo processor (117) for an ultrasound imaging device (102) includes a frame processor (118) that aligns a plurality N of sequentially received frames of echoes based on a set of motion displacement fields for the plurality of frames and combines the aligned plurality of sequentially received frames, thereby forming a compounded frame, wherein each displacement field is based on a displacement between a most recently acquired frame of the plurality of frames corresponding to a latest angle of insonation and another of the plurality of frames acquired at the latest angle of insonation. A method includes obtaining a set of frames of echoes acquired at different times, determining a motion displacement field based on at least two of the frames of the set, motion-compensating all of the frames of the set based on the displacement field and previously determined displacement fields, and generating a compounded frame based on the motion-compensated frames, wherein the displacement field is determined based on the most recently acquired frame and a previously acquired frame, both frames having a same angle of insonation.

摘要： A method includes receiving first electrical signals from a first single -element transducer (112 1 ) and second electrical signals from a second single-element transducer (112 2 ). The transducers are disposed on a shaft (110), which has a longitudinal axis (200), of an ultrasound imaging probe (102) with transducing sides disposed transverse to and facing away from the longitudinal axis. The transducers are angularly offset from each other on the shaft by a non-zero angle. The transducers are operated at first and second different cutoff frequencies. The shaft concurrently translates and rotates while the transducers receive the first and second ultrasound signals. The method further includes delay and sum beamforming, with first and second beamformers (120 1 , 120 2 ), the first and second electrical signals, respectively via different processing chains (712 1 , 712 2 ), employing an adaptive synthetic aperture technique, producing first and second images.

摘要： A method is disclosed for determining a flow acceleration directly from beamformed ultrasound data, i.e. independent of velocity estimates. The method includes extracting data from two different times and a same position, or two different positions and a same time, from the beamformed ultrasound data, and producing cross- correlation data to directly estimate the flow acceleration.

An apparatus includes a beamformer (112) configured to process electrical signals indicative of received echoes produced in response to an interaction of a transmitted ultrasound signal with tissue and generate RF data, and an acceleration flow processor (114) configured to directly process the RF data and generate a flow acceleration therefrom.
