Color Doppler
Color Doppler is a technique in which colors superimposed on an image of a blood vessel indicate the speed and direction of blood flow in the vessel. Colour doppler test is a type of ultrasound test.

Doppler ultrasound works by measuring sound waves that are reflected from moving objects, such as red blood cells. This is known as the Doppler effect.

There are different types of Doppler ultrasound tests. They include:

  • Color Doppler - This type of Doppler uses a computer to change sound waves into different colors. These colors show the speed and direction of blood flow in real time.
  • Power Doppler - A newer type of color Doppler. It can provide more detail of blood flow than standard color Doppler. But it cannot show the direction of blood flow, which can be important in some cases.
  • Spectral Doppler - This test shows blood flow information on a graph, rather than color pictures. It can help show how much of a blood vessel is blocked.
  • Duplex Doppler - This test uses standard ultrasound to take images of blood vessels and organs. Then a computer turns the images into a graph, as in spectral Doppler.
  • Continuous wave Doppler - In this test, sound waves are sent and received continuously. It allows for more accurate measurement of blood that flows at faster speeds.

The Color Droppler machine at Health Plus Diagnostic quickly brings you quantifiable information across a wide variety of patients – even those with body types or conditions that make them difficult to scan. GE’s XDclear* probe technology pairs with our new imaging platform to capture data from every channel in the probe.
