Patent ID: 8362771

Claim:
A method for measuring field inhomogeneities and setting shim parameters of a magnetic resonance apparatus, comprising the steps of: moving a patient, having an examination region from which magnetic resonance data are to be acquired, on a displaceable bed through an imaging region of a magnetic resonance data acquisition unit by continuous displacement of the patient bed; during said continuous displacement of the patient bed and the patient thereon, acquiring information representing field inhomogeneities of a basic magnetic field generated by the data acquisition unit, at multiple positions of the patient bed from respective magnetic resonance signals generated at said positions, by excitation of multiple slices in the examination region before reading out echoes from a first of said multiple slices, with one echo train, comprising multiple echoes, being generated per excitation; supplying the measured information to a processor, and in said processor, calculating adjustments to shim parameters of the magnetic resonance apparatus dependent on the measured information, thereby generating adjusted shim parameters at an output of the processor; and implementing a magnetic resonance examination of the examination subject to acquire magnetic resonance imaging data therefrom with the magnetic resonance apparatus shimmed according to the adjusted shim parameters.
