Zusammenfassung:A magnetic resonance imaging (MRI) device (200) for imaging a volume includes a main magnet for generating a magnetic field, an insulator sheet (140) formed into a tube extending along an axis, a gradient coil (50) disposed on an outside surface defining the tube for manipulating the magnetic field generated by the main magnet to image the volume, and a cooling circuit disposed between the gradient coil (50) and a RF coil (72). The cooling circuit is disposed on an opposite inside surface defining the tube, wherein the cooling circuit shields the gradient coil (50) from the RF coil (72) while cooling the gradient coil (50).
