1. An ultrasound image processing device for quantitative analysis of cardiac motion, comprising:
a display; and
a processor configured to:
obtain an ultrasound presentation, wherein the ultrasound presentation comprises one of an ultrasound image and an ultrasound video;
perform a motion tracking on at least one region of interest in a myocardial tissue according to the ultrasound presentation to obtain tracking results of a plurality of local sub-regions formed by dividing the at least one region of interest;
determine confidence values of the tracking results of the plurality of local sub-regions of the at least one region of interest as tracking qualities of the tracking results;
control the display to display the confidence values of the tracking results of the plurality of local sub-regions of the at least one region of interest;
generate tracking quality indicators of the plurality of local sub-regions according to the tracking qualities of the tracking results of the plurality of local sub-regions, wherein each of the plurality of local sub-regions has a respective tracking quality indicator;
arrange the tracking quality indicators of the plurality of local sub-regions of the region of interest in an anatomical shape of the region of interest in a form of color coding according to an anatomical structure of the region of interest and the plurality of local sub-regions, wherein each of the plurality of local sub-regions corresponds to a color coded block, and different local sub-regions correspond to color coded blocks with different colors, wherein:
the tracking quality indicator of each local sub-region is represented by a shade of a color of a contour line surrounding the corresponding color coded block, and different shades of the color correspond to different confidence values; or
the tracking quality indicator of each local sub-region is represented by a texture pattern filled in the corresponding color coded block, and different texture patterns correspond to different confidence values; and
control the display to display the tracking quality indicators arranged in the anatomical shape of the region of interest.
