Abstract
Embodiments of the present invention provide a motion monitoring method during MR imaging, comprising: acquiring a noise of a receiving coil before or after each imaging repetition time of an imaging scanning sequence; determining main coil channels associated with a motion of a scanned object in the receiving coil; determining a sum of squares of amplitudes of noises of the respective main coil channels; and filtering the sum of squares of amplitudes of noises of the main coil channels to obtain a motion track of the scanned object.
