Automated Detection of Motion Artefacts in MR Imaging Using Decision Forests

Figure 7

Effects of respiratory motion on the heart. (a), (b), (c), and (d) show scans from a Cartesian acquisition, (e), (f), (g), and (h) from a radial acquisition, and (i), (j), (k), and (l) from a spiral acquisition. The captions indicate the number of breathing cycles that the subjects completed during the acquisition, exposing different levels of artefacts.
