In ultrasound, sonographers use Doppler Effect to measure a patient’s blood flow velocity. Red blood cells reflect sound waves produced by a Doppler. The waves & frequency varies with the flow velocity. Continue reading about Doppler Effect and how it plays a vital role in measuring blood flow velocity. What is Doppler Effect? Have you ever been standing…
Avoiding aliasing is every sonographer’s goal in ultrasound imaging to get accurate and reliable information on a patient. There are various ways of evading aliasing that all sonographers must know. Today, we provide in-depth info on the use of continuous wave Doppler. What is Doppler Effect? Doppler Effect is the variation of sound frequency due…
Most sonographers encounter aliasing with pulse spectral Doppler or color Doppler. Pulsed ultrasound doesn’t have a particular upper limit for displaying the Doppler shift. It’s commonly known as the Nyquist limit. High-velocity blood circulation causes Doppler shifts beyond the Nyquist limit resulting in aliasing. Often, aliasing is visible as a bright and turbulent flow in…
A broad range of clinical applications, especially prenatal diagnosis, make use of diagnostic ultrasound. So far, there are no recorded incidences of any harm caused to humans or the developing fetus as a result of diagnostic ultrasound. The excellent safety records notwithstanding, ultrasound imaging should only be carried out by individuals who are fully trained…
