Colour Doppler

Color Doppler is a medical imaging technique that uses ultrasound to visualize the flow of blood through vessels in the body. It is a type of Doppler ultrasound that uses color to display blood flow velocity and direction.

During a color Doppler ultrasound, a transducer sends high-frequency sound waves into the body and receives the echoes that bounce back. The machine then processes the echoes to create images of the blood vessels and the flow of blood within them. The color display is used to show the direction of blood flow, with blue indicating flow away from the transducer and red indicating flow toward it.

Color Doppler is commonly used to evaluate blood flow in the heart, blood vessels, and other organs. It is a non-invasive and painless procedure that does not involve radiation, making it a safe diagnostic tool for a variety of conditions.
