In physics, Continuous-wave (CW) Doppler is an ultrasound technique that continuously transmits and receives sound waves. This allows for the measurement of very high blood flow velocities, crucial in medical diagnostics where precise speed is paramount. Unlike pulsed-wave Doppler, CW Doppler doesn’t suffer from aliasing, making it ideal for assessing rapid, turbulent flows in conditions like severe valvular stenosis or shunts.
For medical ultrasound, CW Doppler is particularly valuable for accurately quantifying blood flow in the heart and major vessels. Its ability to detect extreme velocities provides essential diagnostic information for cardiologists and vascular specialists, ensuring comprehensive hemodynamic assessments without the limitations of depth or speed that affect other Doppler modalities.
