摘要:
A system and method for a magnetic resonance (MR) imaging system includes a coil form, at least one magnet positioned about the coil form and configured to generate a magnetic field, at least one gradient coil for manipulating the magnetic field generated by the at least one magnet by way of a gradient field, and a heat pipe thermally connected to the coil form and having a cryogen therein. The MR imaging system also includes a cryocooler connected to the heat pipe to cool the heat pipe and the cryogen, wherein the coil form is comprised of a thermally conductive material in which eddy currents are substantially reduced during operation of the at least one gradient coil. The present invention has been described in terms of the preferred embodiment, and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.
