In a method and device for side-band suppression, a positive eddy current correction factor and negative eddy current correction factor are determined and scanning N/2 times by a positive gradient takes place, and the positive gradient scanning signal is collected during each scan. Scanning N/2 times by a negative gradient also takes place, and the negative gradient scanning signal is collected during each scan. N is an even number. An eddy current correction of the N/2 positive gradient scanning signals collected according to the positive eddy current correction factor is performed as an eddy current correction of the N/2 negative gradient scanning signals collected according to the negative eddy current correction factor.

In a method and device for correcting distortion in MRI, k-space data are acquired in a number of data readout directions, the data are converted into a number of images, and a corresponding pixel shift map is generated for each image. The geometric distortion in the corresponding image is corrected according to the pixel shift map, and then all geometric distortion-corrected images are combined. Since movement distortion normally exists in the data readout direction, collecting the k-space data from a number of data readout directions can effectively correct movement distortion. Moreover, correcting the geometric distortion for the images converted from data acquired in a number of data readout directions according to the pixel shift map can reduce the geometric distortion of the final image generated from combination of images. The method and device correct not only movement distortion of MRI images, but also geometric distortion of MRI images.
