摘要
A cryogenic device for cooling an RF coil of a Magnetic Resonance Imaging scanner. The cryogenic device includes: a cryocooler providing a cold source; a solid thermal link; the solid thermal link in thermal contact with the cryocooler; a RF coil holder for holding the RF coil, the RF coil holder being in thermal contact with thermal link; a vacuum chamber enclosing the solid thermal link and the RF-coil holder; a measurement surface, facing the RF coil holder; wherein each one of the cryocooler, the solid thermal link, the RF coil holder and the measurement surface is magnetic material free.
