ABSTRACT:
A magnetic resonance imaging (MRI) device for imaging a volume includes a main magnet for generating a magnetic field, an insulator sheet formed into a tube extending along an axis, a gradient coil 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 and a RF coil. The cooling circuit is disposed on an opposite inside surface defining the tube, wherein the cooling circuit shields the gradient coil from the RF coil while cooling the gradient coil.
