1. A computer-implemented method for determining false motion tracked by a motion correction system during a medical imaging scan, the method comprising: obtaining tracking data, wherein the tracking data reflects motion of a subject of the medical imaging scan or a portion thereof; determining by a false motion discriminator a likelihood of the obtained tracking data reflecting false motion, wherein the false motion is not reflective of true motion of the subject of the medical imaging scan or the portion thereof; and generating by the false motion discriminator a confidence level of the determined likelihood of the obtained tracking data reflecting false motion, wherein the motion correction system is configured to adjust output based on the confidence level, wherein the false motion discriminator comprises a computer processor and an electronic storage medium.
