ABSTRACT:
In a method for determining a compensation setting for an eddy current field that is caused by a temporally variable gradient field of a magnetic resonance apparatus, at least two magnetic resonance data sets arising from different spatial positions are generated using the gradient field, and from the magnetic resonance data sets, the compensation setting of a filter is calculated, with which a control quantity of the gradient field can be pre-distorted, such that the sum from the gradient field and at least one component of the eddy current field exhibits a desired time curve, and the gradient field used for the magnetic resonance data sets is generated with a predetermined initial setting of the filter that at least approximately takes into account the component of the eddy current field.
