Abstract: Spike noise in a k-space dataset acquired in magnetic resonance imaging may be removed by generating a mask including a set of data points which constitute spike noise in the k-space dataset based on the acquired k-space dataset via a trained deep learning network, the mask corresponding to a location of the spike noise in the acquired k-space dataset. An image reconstructed based on the acquired k-space dataset and the mask may be displayed.

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.
