Cryostat Structure for Magnetic Resonance Imaging Apparatus, and Magnetic Resonance Imaging Apparatus

Abstract

The present invention 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.
