A Doppler Ultrasound Machine is a non invasive testing machine that can be used to estimate the blood flow through your blood vessels by bouncing high-frequency sound waves (Ultrasound) off circulating red blood cells.
Doppler Ultrasound, uses a special application of ultrasound to measure the direction and speed of blood cells as they move through vessels. The movement of blood cells
causes a change in pitch of the reflected sound waves (called the Doppler Effect).
