Spurious Signals

Artefacts are spurious signals that do not represent true signals or physical structures. It is important to differentiate artefacts from genuine signals in ultrasound studies as this may help avoid misinterpretations and measurement errors. The nature of many Doppler ultrasound artefacts is similar to 2D echocardiography artefacts, including inappropriate gain settings, mirror artefacts, and reverberation artefacts. However, as Doppler ultrasound is used to detect blood flow and myocardial velocity, it is susceptible to insonation (Doppler) angle error, aliasing, and other velocity-related artefacts. These will be presented in this chapter as two main types of artefacts: one that is related to spectral Doppler, and the other related to colour-flow Doppler ultrasound.
