Identifying radio frequency interference in a magnetic resonance system

A non-transitory computer program product configured to be loaded directly into a memory of a control device of a magnetic resonance tomography system, wherein the computer program product, when executed in the control device of the magnetic resonance tomography system, is configured to cause the magnetic resonance tomography system to:

• perform an acquisition, in which a scan of a k-space along a trajectory takes place, wherein an angle of rotation exists between a scan start position of a first individual acquisition and a scan start position of a second individual acquisition;
• obtain a first image from the first individual acquisition;
• obtain a second image from the second individual acquisition, such that the second image is rotated about the angle of rotation with respect to the first image;
• rotate one of the first or second images in respect of the other image about the angle of rotation such that image frames of the first image and the second image lie on top of one another to define overlapped images;
• determine a correlation between the one rotated image and the other image based on an artifact located in a same image position in the overlapped images;
• and
• identify a point of radio frequency (RF) interference from the correlation.
