One of the barriers for using Prospective Motion Correction (PMC) in the clinic is the unpredictable nature of a scan because of the direct interference with the imaging sequence. Here, we suggest using the framework of retrospective motion correction to reverse the effects of prospective motion correction (reverse retrospective correction) for brain scans. The most important impact will most likely be in the clinical application, where our approach guarantees that a data set can be presented whose quality is at least as good as a scan acquired without PMC.
