Embodiment Construction

[0020] Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference symbols are used throughout the drawings to refer to the same or like parts. Although embodiments of the invention have been described as intended for use with superconducting magnets contained in MRI machines, the invention is also broadly applicable to the cooling of superconducting magnets, independent of the specific end use of the superconducting magnet. Superconducting magnets may also be implemented in other types of medical imaging devices, as well as non-medical imaging devices.

[0021] As used herein, "thermally coupled," "thermally connected," and "thermally communicating" means that two physical systems or components are related in such a way that thermal energy or heat can be transferred between such systems or components. For example, such thermal communication may be through...

Abstract

A cooling system includes a first cooling loop having a first cooling fluid configured for circulation therethrough and a second cooling loop having a second cooling fluid configured for circulation therethrough. The first cooling loop is in thermal communication with the superconducting magnet and is configured to provide primary cooling for the magnet, and the second cooling loop is in thermal communication with the superconducting magnet and is configured to provide secondary cooling for the magnet.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Patent Application No. 14 / 584,069, filed December 29, 2014, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the invention relate generally to magnetic resonance imaging, and more particularly to cooling systems and methods for magnetic resonance imaging devices. Background technique [0004] Magnetic resonance imaging (MRI) machines work by generating very strong magnetic fields using superconducting magnets, which consist of many coils, or windings, of wire through which electric current is passed. Harnessing superconductivity to create strong magnetic fields involves reducing the electrical resistance in a conductor carrying an electrical current to almost zero by cooling it to ultra-low temperatures below the limit of superconductivity. This can be done by immersing the coil in a bath of liquid cryogen, such as liquid helium, ...
