    摘要: In a gradient coil and a method to manufacture a gradient coil for a magnetic resonance apparatus, the gradient coil has at least one saddle coil, the saddle coil having a spatially shaped, electrically conductive plate with a line-shaped recess penetrating the plate. Conductor structures that create a gradient magnetic field in an examination region when a current signal flows therethrough are formed by the recess and by the shaping of the plate. The recess is filled with an electrically insulating material before implementation of the spatial shaping.

    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.
