    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 device is disclosed for superposed magnetic resonance and positron emission tomography imaging. In at least one embodiment the device includes a gradient coil and a positron emission tomography unit (PET unit). The PET unit is arranged within the gradient coil and has a first shield against radiofrequency radiation which in part surrounds the PET unit, and a second shield against radiofrequency radiation is arranged on the gradient coil. The first shield is connected to the second shield to form a shield which is at least partly closed. This makes a closed shield for the PET unit possible, which nevertheless is still easily accessible for maintenance purposes due to the two-part design of the shield.
