The invention provides a method for obtaining a 3D vector flow field from color Doppler ultrasound data. The method includes obtaining color Doppler ultrasound data from a plurality of acquisition locations, wherein the plurality of acquisition locations comprises a target acquisition location and one or more additional acquisition locations, wherein the one or more additional acquisition locations is adjacent the target acquisition location. A 3D vector flow field is then derived from the obtained color Doppler ultrasound data.

Methods and systems for obtaining a 3D vector flow field

The invention provides a color Doppler ultrasound imaging method. The method includes acquiring a plurality of sparse color Doppler ultrasound image frames and B-mode ultrasound image frames. The color Doppler and B-mode image frames are then pre-processed before estimating a vector flow based on said frames by means of solving a flow vector field in a whole field of view of the image frames through an optimization framework, in which a mask is adapted to define a sparse area of observed color Doppler measurements within the sparse color Doppler image frames. A new color Doppler image frame is generated based on this estimate and included in the output image.

Methods and systems for performing color doppler ultrasound imaging

A method in accordance with the present disclosure may include transmitting a plurality of ultrasound pulses toward a medium from a transducer array, wherein the plurality of ultrasound pulses includes a sequence of a Doppler burst (--) comprising a plurality of unfocused first pulses () and a B-mode burst comprising one or more second pulses (). The method may further include detecting echoes responsive to the transmitted sequence, wherein the detecting includes simultaneously detecting, within a field of view, FOV, of the array, a set (--) of first echoes responsive to the plurality of unfocused first pulses (), generating Doppler data from signals representative of the set (--) of first echoes, generating B-mode image data from signals representative of echoes responsive to the one or more second pulses (), and simultaneously displaying the Doppler data and B-mode image data.
