A system may comprise a magnetic resonance imaging (MRI) device including a bore that is configured to accommodate a subject. The MRI device may include multiple superconducting magnets configured to generate a magnetic field in the bore. The MRI device may include one or more superconducting connections each of which is configured to connect at least two of the multiple superconducting magnets. The system may further include a radiation source configured to emit a radiation beam toward the bore. The radiation source may be able to rotate in a plane perpendicular to a direction of the magnetic field in the bore. The MRI device may further include one or more protection components configured to prevent at least a portion of the radiation beam from irradiating the one or more superconducting connections.

Systems and methods for diagnosis and image guided therapy with superconducting magnet shielding and providing heat exchange

The present disclosure relates to a system and a method. The system may include a magnetic resonance imaging (MRI) apparatus configured to acquire MRI data with respect to a region of interest (ROI) and a therapeutic apparatus configured to apply therapeutic radiation to at least one portion of the ROI.

Radiation therapy system and method

A superconducting magnet assembly may include a switch component including a first thermal switch and/or a second thermal switch. The first thermal switch may include a first activation mode configured to facilitate heat transfer between a first stage cold head and a radiation shield, and a first deactivation mode configured to break or impede the heat transfer between the first stage cold head and the radiation shield. The second thermal switch may include a second activation mode configured to facilitate heat transfer between a second stage cold head and a superconducting magnet, and a second deactivation mode configured to break or impede the heat transfer between the second stage cold head and the superconducting magnet.

Superconducting magnet assembly

The present disclosure relates to a system and a method. The system may include a first device including a treatment head configured to emit a radiation beam. The system may include a second device comprising a body. The body may include one or more openings at a bottom of the recess that allow passage of the radiation beam substantially free of the interference by the body.

Therapeutic system and method

The present disclosure relates to a therapeutic apparatus including an MRI apparatus configured to acquire MRI data with respect to a region of interest. The MRI apparatus may include a plurality of main magnetic field coils coaxially arranged along an axis. The MRI apparatus may also include a plurality of shielding coils arranged coaxially along the axis. A current within at least one of the shielding coils may be in the same direction with a current within the main magnetic field coils.

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.
