An ultrasound imaging system includes a transducer array () with a plurality of transducer elements () configured to transmit a pulsed field beam into a scan field of view, receive echo signals produced in response to the pulsed field interacting with particles/structure flowing/moving in the scan field of view, and generate electrical signals indicative of the echo signals. The ultrasound imaging system further includes a beamformer () including multiple synthetic transmit aperture beamformers configured to process the electrical signals over a plurality of processing channels () into corresponding receive-beams of RF-data with a beam-level delay, channel-level delays, a beam-level gain and channel-level gains. The ultrasound imaging system further includes a velocity processor () configured to estimate a flow velocity of the structure flowing in the scan field of view from the RF-data. The ultrasound imaging system further includes a rendering engine () configured to display the flow velocity estimate on a display () with color-coding.

High resolution compound ultrasound flow imaging

An ultrasound imaging system () includes a velocity processor () that processes ultrasound data representing structure flowing through a tubular object and generates vector flow imaging information indicative of the structure flowing through a tubular object based thereon. The vector flow imaging information includes an axial velocity component signal and a lateral component signal, and the axial and lateral component signals indicate a direction and a speed of the structure flowing through the tubular object. The ultrasound imaging system further includes a flow parameter processor () that determines at least one flow parameter based on the vector flow imaging information and generates a signal indicative thereof.

Ultrasound vector flow imaging (VFI) with curve tracing

An ultrasound imaging system includes an ultrasound transducer that receives an echo signal generated in response to an ultrasound signal transmitted by the system interacting with a moving material. Receive circuitry processes the echo signal and produces an electrical signal indicative thereof. Front end electronics amplify and digitize the electrical signal producing M-bit RF data. A beamformer that processes the M-bit RF data and generates N-bit high dynamic range beamformed data. N is greater than M. The system further includes pre-processing circuitry that converts the N-bit data RF to 2&#xd7;K-bit I/Q data. K is less than M. A velocity processor determines a phase estimate of the moving material from the I/Q data. A rendering engine visually presents the phase estimate.

High dynamic range ultrasound flow imaging system

An ultrasound imaging system includes a transducer array, with an array of transducer elements that transmits an ultrasound signal and receives a set of echoes generated in response to the ultrasound signal traversing a flowing structure. The ultrasound imaging system further includes a beamformer that beamforms the set of echoes, generating a beamformed signal. The ultrasound imaging system further includes a pre-processor that performs basebanding, averaging and decimation of the beamformed signal and determines an autocorrelation of the basebanded, averaged and decimated beamformed signal. The ultrasound imaging system further includes a velocity processor that generates an axial velocity component signal and a lateral velocity component signal based on the autocorrelation. The axial and lateral velocity components indicate a direction and a speed of the flowing structure in the field of view.
