Doppler ultrasound - a non-invasive test that can depict blood flow. A Doppler probe within the ultrasound transducer evaluates the velocity and direction of blood flow in the vessel by bouncing high-frequency sound waves off of red blood cells.

1. A technique used early in high-risk pregnancies to check the blood flow through the fetus's umbilical cord.
2. Pocket-sized handheld device which can be used to listen to the babies heartbeat during pregnancy.

Doppler ultrasound
A special form of ultrasound that uses sound waves to measure the velocity of blood flow. Doppler ultrasound can be used to listen to the fetal heart beat, examine the fetal heart for defects, and estimate placental blood flow.

Another form of Doppler ultrasound, known as a CTG (cardiotocograph), can be used to make sure your babies' hearts are beating normally. Scans can also help to see how your twins are lying, and identify which one is which.
Your provider will also listen for the fetus' heart beat with a Doppler ultrasound. Doppler technology uses sound waves to measure the heart beat and is perfectly safe for you and the baby.
For example a Doppler ultrasound beam aligned to the flow of blood in a vessel has a zero degree of insonation to the flow.
The healthcare provider may also use a Doppler ultrasound. This special type of ultrasound measures blood flow in the blood vessels. It checks movement in organs. One reason to use a Doppler ultrasound is to check the movement of heart valves.

Sometime around week 10 to 12, your doctor may have listened to the baby's heartbeat using Doppler ultrasound, and, in another few weeks, you will probably start feeling little flurries inside.
Alternatively, a colour doppler ultrasound may also be done. In this instance, the colour doppler will be used to visualize the arteries.
'Diagnostic ultrasounds' (that create images) tend to require lower intensities than Doppler ultrasound, used to assess blood flow through the cord and placenta and to listen to the baby's heartbeat.
13 We attempted to achieve an angle close to 0degrees between the Doppler ultrasound beam and the direction of blood flow in each vessel.
