摘要： A method is disclosed for correcting a distortion in a magnetic resonance recording. A distortion indicates a mismatch between a distorted position of an image point in the magnetic resonance recording and an actual position of the image point. According to at least one embodiment of the method, a B0 field deviation and a gradient field deviation are determined for at least one actual position in the magnetic resonance facility. Furthermore, a magnetic resonance recording of an examination object is captured and the actual position of an image point of the magnetic resonance recording is determined as a function of the distorted position of the image point in the magnetic resonance recording, the B0 field deviation at the actual position and the gradient field deviation at the actual position.
