Provided are a cryogen recondensing system and a superconducting magnet apparatus including the same. The cryogen recondensing system includes a primary reservoir that stores cryogen for cooling a superconducting coil; a refrigerator that recondenses gas cryogen of cryogen stored in the primary reservoir; a secondary reservoir that stores gas cryogen; and a secondary reservoir tube that connects the primary reservoir to the secondary reservoir, through which the gas cryogen flows.

Cryogen recondensing system and superconducting magnet apparatus including the same

A magnetic resonance imaging (MRI) acoustic system includes a magnet; an electro-acoustic transducer that includes a coil through which a current flows so that an attractive force or a repulsive force is generated with respect to the magnet, and a vibrating plate that vibrates in response to the attractive force or the repulsive force; and a controller that controls an intensity of a current input to the electro-acoustic transducer according to a position of the electro-acoustic transducer in a magnetic field generated by the magnet.

MRI acoustic system, acoustic output device, and electro-acoustic transducer

Provided is magnetic resonance imaging (MRI) acoustic system that includes a magnet that is included in a bore having an image-taking space where an object is able to be accommodated and that forms a magnetic field in the image-taking space to obtain an MR image of the object, an electro-acoustic transducer that is located outside of the bore, and includes coils through which a current for generating an attraction force or a repulsion force with respect to the magnetic field generated by the magnet and a vibrating plate that vibrates in response to the an attraction force or the repulsion force, and a controller that controls the intensity of the current inputted to the electro-acoustic transducer to generate a sound by using the magnetic field that is generated by the magnet.

A magnetic resonance imaging (MRI) system comprises, a main magnet, a gradient coil and an RF coil. The main magnet generates a static magnetic field, the gradient coil which is formed inside the main magnet and generates a gradient magnetic field and the RF coil. The RF coil is formed inside the gradient coil and comprises a plurality of different components including: a former supporting the plurality of different components including windings and having a first area and a second area and a groove formed in the second area and in which a component of the RF coil is installed and inset, reducing thickness of the RF coil.
