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 preprocessed 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 isgenerated based on this estimate and included in the output image.

Description

technical field [0001] The present invention relates to the field of ultrasound imaging, and in particular to the field of color Doppler ultrasound imaging. Background technique [0002] Color Doppler ultrasound imaging allows the user to visualize flow information along the ultrasound beam. This feature is widely deployed in today's echographic systems. [0003] When one desires to visualize color Doppler ultrasound information in a large field of view, the frame rate typically drops because measurements need to be made at an increased number of spatial points. [0004] To reduce the frame rate penalty, resorting to ultrafast scanning schemes based on planar or diverging waves has been previously proposed. However, this requires a redesign of the ultrafast acquisition sequence and adaptation of the front end of the ultrasound imaging system for ultrafast use. Therefore, this proposal may not be readily usable on existing systems that do not have ultra-fast scanning capab...
