- Doppler effect is the change in frequency of sound wave due to a reflector moving towards or away from an object, which in the case of ultrasound is the transducer1. Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to perform imaging of the movement of tissues and body fluids (usually blood), and their relative velocity to the probe2. During a Doppler ultrasound, a handheld device emits sound waves that bounce off moving objects, such as blood cells. The reflected sound waves create an image of the way the blood is flowing3. The Doppler effect enables ultrasound to be used to detect blood flow and to quantify vascular disease4.Learn more:✕This summary was generated using AI based on multiple online sources.

Doppler Ultrasound: What Is It, Purpose and Procedure Details
- Ultrasound, also called sonography or ultrasonography, is a noninvasive imaging test. A standard ultrasound produces images, but it doesn’t show blood flow like a Doppler ultrasound. The different types of Doppler ultrasounds include: 1. Color Doppler:A computer changes the sound waves into different colors to show the direction of blood flow. 2. S...
