What is Doppler ultrasound?

Doppler ultrasound is used to track the speed of blood flow while imaging the heart and blood vessels.

The test uses sound waves, sent into the body with a handheld device called a transducer that’s about the size of a bar of soap.

The frequency of the returning sound waves corresponds to the speed of the blood cells as they move through the body. At the same time, the ultrasound waves bouncing off the heart and blood vessels are translated into an image of their structure.
