non-invasive imaging technique measuring blood flow using sound waves
Doppler ultrasound, also known as Doppler sonography, is a non-invasive imaging technique that uses high-frequency sound waves to measure the flow of blood through blood vessels. By analyzing changes in the frequency of the sound waves as they bounce off moving blood cells, it helps healthcare professionals assess the health of blood flow and detect conditions such as blood clots, poor circulation, and blockages.
