Knowledge point

Doppler ultrasonography

Doppler ultrasonography employs the Doppler effect to assess whether structures (usually blood)[32] are moving towards or away from the probe, and its relative velocity. By calculating the frequency shift of a particular sample volume, for example flow in an artery or a jet of blood flow over a heart valve, its speed and direction can be determined and visualized. Color Doppler is the measurement of velocity by color scale. Color Doppler images are generally combined with gray scale (B-mode) images to display duplex ultrasonography images.

Color-flow imaging

Color-flow imaging is an enhanced form of Doppler ultrasound technology. In a procedure similar to duplex ultrasound, it uses color to highlight the direction of blood flow. Vessels in which blood is flowing are colored red for flow in one direction and blue for flow in the other, with a color scale that reflects the speed of the flow.It can clearly understand the anatomical shape and activity of large blood vessels, and can visually display the direction, speed, range of blood flow, and whether there are blood flow disorders and abnormal pathways. The speed of blood flow determines the reflection frequency, which is represented by amplitude beam in spectral Doppler. The velocity of blood flow is fast, and the amplitude on the spectrum curve is high; the velocity of blood flow is slow, and the amplitude on the spectrum curve is low, so amplitude can accurately calculate the velocity of blood flow. Color Doppler images are displayed with different brilliance.
