    摘要： A controller of a magnetic resonance system determines an activation signal vector based on a target field predetermined for the controller in conjunction with field characteristics of field coils known to the controller. The activation signal vector includes a respective activation signal for each field coil. The controller determines the activation signal vector such that within a predetermined examination volume of the magnetic resonance system, any deviation of an ideal field that would result if ideal coils were subjected to the activation signals of the activation signal vector from the target field is minimized. The controller determines a compensation signal vector based on the activation signal vector in conjunction with eddy current characteristics of the field coils known to the controller. The compensation signal vector is used to minimize a deviation of an actual field from the target field within the predetermined examination volume of the magnetic resonance system.

    摘要： A method for producing a gradient coil assembly for a magnetic resonance imaging system includes applying a number of primary gradient coils and a number of secondary gradient coils to a winding mandrel to form the gradient coil assembly. A control coil arrangement is associated with the winding mandrel. During an intermediate check before completion of the gradient coil assembly, at least one coupling inductance value between the control coil arrangement and at least one of the primary gradient coils and/or at least one of the secondary gradient coils is determined. An arrangement of the relevant gradient coils on the winding mandrel is corrected as a function of the at least one coupling inductance value.
