Abstract: 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.

Abstract: The invention provides a method for generating a transvalvular pressure quantification within a cavity. The method includes acquiring a plurality of color Doppler ultrasound image frames, wherein the image frames comprise a view of a valve, one of which is then presented to a user. The user may then provide an input to indicate the location of the valve within the image frame. The location of the valve is then tracked within the remaining image frames based on the user input. A vector flow is estimated based on the color Doppler image frames and the tracked location of the valve, which may be used to estimate the flow across the valve(s) and in the cavity.

Abstract: 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.

Abstract: 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 (10-1, 10-2) comprising a plurality of unfocused first pulses (12) and a B-mode burst comprising one or more second pulses (13). 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 (14-1, 14-2) of first echoes responsive to the plurality of unfocused first pulses (12), generating Doppler data from signals representative of the set (14-1, 14-2) of first echoes, generating B-mode image data from signals representative of echoes responsive to the one or more second pulses (13), and simultaneously displaying the Doppler data and B-mode image data.
