Systems and methods for imaging and treatment

A system comprising:

• a magnetic resonance imaging (MRI) device configured to perform an imaging of a subject, wherein
• the MRI device includes a cryostat;
• the cryostat includes a first cooling chamber and a second cooling chamber;
• and
• the first cooling chamber and the second cooling chamber are in gas communication through a connection conduit;
• and
• a radiation source configured to emit a radiation beam toward the subject, the radiation source being positioned between the first cooling chamber and the second cooling chamber such that the first cooling chamber and the second cooling chamber are outside of a radiation range of the radiation beam, wherein
• the connection conduit is positioned out of a rotation range of the radiation source.

• a first end of the connection conduit is located inside a portion of the first cooling chamber filled with a gaseous-state cooling medium;
• and
• a second end of the connection conduit is located inside a portion of the second cooling chamber filled with the gaseous-state cooling medium;
