PROBLEM TO BE SOLVED: To provide a dynamic magnetic resonance imaging method which can complete an image with a small reconstruction time and is robust against motion artifact, magnetic field ununiformity, and sub-scanning of a k-space. SOLUTION: A plurality of incomplete sub-data sets 67 are recorded for partial data sets 63 and a record of each incomplete sub-data set 67 is allocated to one individual image. Recording of the incomplete sub-data sets 67 is carried out by different scanning patterns alternating along a scanning grid attached to the partial data sets 63. Grid points with different scanning grid attached to the partial data sets 63 are scanned in different scanning patterns. Complete sub-data sets are reconstructed from at least partially incomplete sub-data sets 67 of the partial data sets 63. At least a part of the complete sub-data sets allocated to individual images in respective individual images is used for the reconstruction. Thus individual images are reconstructed.
