Abstract

A method for correcting inhomogeneity of the static magnetic field generated by a magnetic structure, particularly of the static magnetic field generated by the magnetic structure of an MRI system comprising the steps of generating a statistical model of a shimmed magnet structure of the same kind of a target magnet structure to be shimmed, the said statistical model is generated as a function of historical data which describing the features of shimming processes carried out on identical magnets.The statistical model is used to guide in an objective way choices which the persons carrying out a shimming process are faced with between at least two alternative solutions of a minimization algorithm between the magnetic field having a target homogeneity and e magnetic field of the non-shimmed magnet structure combined with the magnetic field generated by a set of magnetic correction elements.Also a system is disclosed for carrying out the method.
