K-Space Tool: Random Motion Artefacts
There are two simulated motion artefacts in this k-space, marked by the blue arrows. Note that one of the movements has occurred whilst the central lines of k-space were being acquired. This results in the strong ghost in the image. The effect of the other movement is much smaller, and is harder to distinguish in the image. This is because it occurred "further out" in k-space, where the effect is more on the fine detail than on contrast.
