FIELD: medicine.
SUBSTANCE: invention relates to medical technology, namely to ultrasound diagnostic imaging systems. System that generates color images of the flow and movement speed comprises an ultrasonic probe having an array of transducers for transmitting ultrasonic energy and receiving ultrasonic echoes from a location containing a moving tissue or fluid, a Doppler processor, to generate measurements of tissue movement speed or blood flow velocity, a quantitative motion estimation processor converting speed measurements into a plurality of different colors for a color Doppler image, graphics processor that generates a color indicator for displaying along with a color Doppler image, color indicator has a final speed level and a reference level for zero speed. Colors of the color indicator are arranged to demonstrate a distinct color transition at a point between the reference level and the final speed level, and a distinct color transition corresponds to a speed from the speed range in which an isospheric surface is displayed on the color Doppler image, display device coupled to a graphics processor and a motion quantification processor displaying a color Doppler image along with a color indicator, colors at both the final speed level and the reference level are zero-speed colors.
EFFECT: use of the system makes it possible to improve the discrimination of the isospheric surface.
