At IVCNZ in 2005, we presented “Correcting motion artifacts in magnetic resonance images”. In that paper we described a new algorithm, TRELLIS, which our group had developed to detect and correct bulk motion in certain types of magnetic resonance (MR) images. A similar algorithm, PROPELLER, has become the method of choice in MR imaging, but a lot more work has occurred since 2005 in the area. The paper briefly recaps on PROPELLER and TRELLIS and then reviews the methods that have been proposed in the intervening period. It is clear that much work remains in the area of motion detection and correction as other aspects of MR imaging continue to improve. Researchers with a range of expertise are needed to collaborate in this work.
