The present disclosure provides a cryostat structure for a magnetic resonance imaging device and a magnetic resonance imaging apparatus comprising the same. The cryostat structure including: a casing which forms a ring-shaped chamber inside; a refrigerant container disposed in the chamber and housing a superconducting coil, so that the superconducting coil is immersed in the liquid refrigerant; a heat shield layer disposed between the casing and the refrigerant container for shielding heat radiation from the casing; the casing has a suction hole which is detachably sealed by a sealing cover, and an adsorption chamber is provided on one side of the casing facing the ring-shaped chamber, and an adsorbent capable of adsorbing overflowing elements from the casing or the refrigerant container or the heat shielding layer is contained in the adsorption chamber.

Cryostat structure for magnetic resonance imaging apparatus, and magnetic resonance imaging apparatus

A superconducting magnet arrangement including: an outer vacuum container (OVC) housing magnet coils; a cryogen vessel thermally linked to the magnet coils; a cold head sock accommodating a cold head, with a thermal contact provided between the cold head and the magnet coils; tubes linking the interior of the cryogen vessel with the interior of the cold head sock; and a thermosiphon circuit defined by the cryogen vessel, the tubes, and the cold head sock. Pre-cooling and removal of ice build-up may be performed using the thermosiphon circuit.
