Abstract
A support rod for supporting structures in a cryostat of a magnetic resonance system. The support rod has oppositely disposed stainless steel heads mounted on a glass reinforced plastic rod. The heads have threads on the main body thereof to minimize the length of the heads and thereby minimize heat condition.
Claims5
A support rod in combination with a cryostat for supporting a superconducting magnet within said cryostat, said support rod comprising:
- a rod like mid-section of material of low thermal conductivity,
- a first head section of higher thermal conductivity disposed at the other end of said support rod,
- a second head section of higher thermal conductivity disposed at the other end of said support rod,
- said first and second head sections being threaded to anchor said support rod between a supporting member on the cryostat and said supported magnet,
- said supporting member mounted on the outside of said cryostat so as to minimize the length of said head sections relative to said mid section inside said cryostat, and thermally reduce the heat transfer between the cryostat and the environment,
- said mounting on the outside of said cryostat enabled by said first and second head sections each being cylindrically shaped and having a single external diameter for the entire length.

A support rod in combination with a cryostat for supporting superconducting magnet within said cryostat,
- said support rod comprising a rod-like extended section of material of low conductivity,
- a first head section of higher thermal conductivity rigidly coupled by crimping at one end of said support rod,
- a second head section of higher thermal conductivity rigidly coupled by crimping at the other end of said support rod,
- a first head section of higher thermal conductivity rigidly coupled by crimping at one end of said support rod,
- external threading on said head sections for connecting said support rod between a supporting member external to said cryostat and said superconducting magnet to support said superconducting magnet, and
- said first head section being entirely external to the cryostat with the superconducting magnet of said system supported by said support member,
- said first and second head sections having a cylindrical shape with a single diameter, to enable said first head section to be entirely external to the cryostat with the superconducting magnet of said system supported by said support member, and to thermally reduce the heat transfer between the cryostat and the environment.
