Artifacts due to enhancement, reverberation, and multi-path reflection are commonly encountered in medical ultrasound imaging. These artifacts can adversely affect an automated image quantification algorithm or interfere with a physician's.
Ultrasound artifacts can distort medical images, leading to misdiagnoses if not properly addressed. This guide explains common artifacts like acoustic shadowing, reverberation, tissue-related issues, and motion artifacts, along with practical solutions to improve image quality and diagnostic accuracy.
The color flash artifact occurs where movement of the fetus or tissue is erroneously translated to flow, evidenced by even tiny motion of the fetus or probe appearing as blurry "bleeding" into the tissue (Fig. 3 c). Both artifacts become more prominent with further reductions of the PRF.
Now, in this short write-up on the Top Ten Doppler (Color and Spectral) Errors and Artifacts, I clearly will not be able to provide all of the contextual physics which makes artifacts valuable or most easily avoided when not beneficial, but I can at least give you a starting point for thought. So this is my list of the top ten errors and artifacts which occur in color and spectral Doppler.

The color flash artifact occurs where movement of the fetus or tissue is erroneously translated to flow, evidenced by even tiny motion of the fetus or probe appearing as blurry "bleeding" into the tissue (Fig. 3 c). Both artifacts become more prominent with further reductions of the PRF.
DOPPLER ARTIFACTS pulsating vessel walls and moving structures (heart) can create small Doppler shifts.
The color flash artifact is a commonly encountered artifact on color Doppler ultrasound, representing spurious flow signal arising due to tissue/transducer motion. Physics The flash artifact is caused by movement of reflective tissues (e.g. due.
The color flash artifact in medical ultrasound appears as a burst of color, typically red and blue, within a fluid-filled structure or region of interest, without actual blood flow. This common artifact is generated by sudden tissue or transducer movement, causing rapid changes in the received Doppler signals, which the ultrasound system misinterprets as blood flow. Recognizing this artifact.

1. Aliasing occurs when the Doppler shift is higher than half the pulse repetition frequency, causing signals to become indistinguishable and display with the wrong color or velocity. It can be corrected by increasing the pulse repetition frequency or adjusting the baseline. 2. Mirror artifacts occur when the ultrasound beam reflects off a structure like bone or diaphragm before returning to.
