doppler ultrasound
Blood flow imager
Doppler ultrasound is a medical imaging technique that measures blood flow by detecting changes in the frequency of sound waves as they bounce off moving blood cells.
The same principle explains why an ambulance siren changes pitch as it passes—the Doppler effect.
Doctors use it to assess circulation, detect blockages, and monitor fetal heartbeats: The doppler ultrasound showed reduced blood flow to the kidney.
