Claim One:
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, the movement of the examination area being a cyclical movement and the number of MR images are recorded in different time segments of the cyclical movement; and determining the motion-corrected PET image from the recorded PET events using the calculated at least two-dimensional movement information, the determining including, generating time segment PET images for the different times segments of the cyclical movement, a respective time segment PET image of the time segment PET images is generated on the basis of the PET events occurring in the associated time segment, the generated time segment PET images being associated with movement segment information of the at least two-dimensional movement information, and correcting the time segment PET images with the associated movement segment information such that a corrected time segment PET image appears for each time segment of the cyclical movement, in which the movement occurring in the associated time segment is corrected.
