Color Doppler is a medical imaging technique that uses ultrasound technology to visualize and assess blood flow within the body. It is a non-invasive procedure that provides real-time images and information about the direction, speed, and characteristics of blood flow in various blood vessels.
During a Color Doppler examination, a handheld device called a transducer is placed on the skin over the area of interest. The transducer emits high-frequency sound waves into the body, which bounce off the moving blood cells and return to the transducer as echoes. These echoes are then processed by a computer to create color-coded images that represent the velocity and direction of blood flow.
