The purpose of using color Doppler in sonography is to visualize blood flow and its direction within vessels. This technique utilizes the Doppler effect, which measures changes in frequency of ultrasound waves reflected from moving objects, such as red blood cells. By applying this principle, sonographers can generate colorful representations of blood flow within vessels on the ultrasound images. Different colors typically indicate the direction of flow relative to the transducer; for example, one color may indicate flow towards the transducer, while another indicates flow away from it.

This functionality is crucial in evaluating various vascular conditions, assessing the state of blood flow to organs, and diagnosing potential blockages or abnormalities. With color Doppler, practitioners gain valuable insights into the hemodynamics of the circulatory system, which static imaging alone does not provide.
