    Abstract: 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.

    Abstract: Gradient coil for magnetic resonance (MR) devices has direct cooling by means of cooling lines that are embedded in the coil and through which a cooling agent flows. The cooling lines are arranged substantially parallel to one another, such as parallel to the axis of the gradient coil, and are combined to form heat exchanger modules whose individual cooling lines are coupled with one another so that the maximum length between the inlet and outlet of a module corresponds to twice the longitudinal length of the gradient coil.
