DISPLACER IN MAGNETIC RESONANCE IMAGING SYSTEM

摘要

Some embodiments of the present disclosure relate to a displacer for reducing the consumption of a cryogen used in a superconductive magnet device. The displacer may occupy some space within the cryogen storage cavity or limit the cryogen into a relatively small space surrounding a superconductive coil in the cryogen storage cavity. The displacer may also include a displacer cavity that may be vacuum or contain a cryogen or another substance.

主权项

1. A device comprising:
a first superconducting coil mounted on a first coil former, wherein the first coil former is at least partially accommodated in a first housing; a second superconducting coil mounted on a second coil former; a first storage cavity at least partially defined by the first housing, the first coil former, and the second coil former, wherein the storage cavity is configured to contain a volume of a first cryogen in the liquid state; a displacer defining a first volume within the first storage cavity, wherein at least part of the displacer and at least part of the first superconducting coil are immersed in the first cryogen in the liquid state.
