1. A method for generating a motion-corrected PET image of an examination area in a combined MR-PET system, the method comprising: recording PET events from the examination area in a first recording time frame; recording a number of MR images of the examination area in at least the first recording time frame; calculating an at least two-dimensional movement information of the examination area on the basis of the recorded number of MR images, wherein the at least two-dimensional movement information describes the movement of the examination area during the first recording time frame; and determining the motion-corrected PET image from the recorded PET events using the calculated at least two-dimensional movement information.
