Claim One:
1. A method for correction of truncations of an image of an object under examination in the reconstruction of image data from raw data which has been recorded with a magnetic resonance system from a field of view of the magnetic resonance system, wherein the object under examination, located in the field of view of the magnetic resonance system, is imaged in the raw data and the image of the object under examination, recorded by the raw data, is truncated at the edge of the field of view such that at least one part of the object under examination is located outside the field of view, the method comprising: determining a number of one-dimensional projections of the imaged field of view in the Radon space from the recorded raw data in order to obtain, for each one dimensional projection, a projection profile of the imaged object under examination over the field of view; checking each projection profile to determine whether the projection profile exhibits a truncation which is caused by the at least one part of the object under examination being located outside the field of view; expanding, upon determining that a respective checked projection profile exhibits a truncation, the respective projection profile by correcting the truncation by the projection profile being extrapolated in accordance with an extrapolation model in an area in which it exhibits the truncation; and reconstructing image data based on the expanded projection profiles, in which the truncation of the image of the object under examination is corrected.
