Claim Text:
1. A method for producing an image of a subject with a magnetic resonance imaging (MRI) system, the steps of the method comprising: a) acquiring k-space data with an MRI system from a subject, wherein when the subject is positioned in a magnetic field of the MRI system the subject causes inhomogeneities in the magnetic field of the MRI system; b) deriving spectral sensitivity information from the acquired k-space data, wherein the spectral sensitivity information relates specific resonance frequencies to distinct spatial locations in the magnetic field of the MRI system based on the inhomogeneities in the magnetic field of the MRI system that are caused by the subject being positioned in the magnetic field; c) reconstructing an image of the subject from the acquired k-space data using the spectral sensitivity information produced in step b) to provide spatial encoding of the image.
