1. A magnetic resonance system configured to correct intra-scan motion during a magnetic resonance scan, the system comprising: a magnetic resonance scanner configured to generate a magnetic field gradient and a radio frequency signal for the magnetic resonance scan; a motion tracking system configured to track one or more pose parameters of a subject and transmit pose data corresponding to the tracked one or more pose parameters at a given time to the magnetic resonance scanner; an electronic memory storage configured to store modules; and a computer processor configured to execute the modules comprising at least: a correction gradient calculation module configured to calculate a moment of a correction gradient to apply to the subject, wherein the moment of the correction gradient is calculated based on the transmitted pose data and a gradient sequence used for the magnetic resonance scan; the magnetic resonance scanner further configured to apply the correction gradient to the subject prior to detecting signals emitted from the subject to correct one or more initial errors in magnetic gradient moment due to movement of the subject during the magnetic resonance scan; and the magnetic resonance scanner further configured to detect the signals emitted from the subject for data acquisition.
