Aliasing in Doppler ultrasound is a display error that occurs when blood flow velocity exceeds the system’s sampling limit (Nyquist limit). It causes inaccurate wrapping of the waveform, often showing reversed or distorted flow. Adjusting scale settings or using a lower frequency can help reduce aliasing and improve diagnostic accuracy. Ultrasound technology has transformed modern … Continue reading Aliasing: Everything You Need to Know (Full Guide)
