Head and Neck Ultrasound - Cigna
static.cigna.com• Doppler US is used to detect moving blood cells or other moving structures and measure their direction and speed of movement. • Color Doppler US uses a computer to convert the Doppler measurements into an array of colors. This color visualization is combined with a standard ultrasound picture of a blood vessel to show the speed

Doppler Ultrasound - Principles and practice
fetalmedicine.orgDoppler ultrasound measures the movement of the scatterers through the beam as a phase change in the received signal. The resulting Doppler frequency can be used to measure velocity if the beam/flow angle is known. Figure 3: Effect of the Doppler angle in the sonogram. (A) higher-frequency Doppler signal is obtained if the
