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

The present invention provides a cryostat structure for a magnetic resonance imaging apparatus and a magnetic resonance imaging apparatus including the same, the cryostat structure comprising: a shell in which an annular chamber is formed; a refrigerant container, which is provided in the chamber, and which accommodates the superconducting coil in the refrigerant container such that the superconducting coil is immersed in a liquid refrigerant; and a heat shielding layer which is arranged between the shell and the refrigerant container and is used for shielding heat radiation from the shell. The shell is provided with an air exhaust hole, the air exhaust hole is detachably blocked by a sealing cover, an adsorption cavity is formed in the side, facing the cavity, of the shell, and an adsorbent capable of adsorbing overflow elements from the shell or the refrigerant container or the heat shielding layer is contained in the adsorption cavity. 本发明提供一种用于磁共振成像设备的低温恒温器构造及具备其的磁共振成像设备，其包括：外壳，内部形成环状的腔室；制冷剂容器，设置于所述腔室内，且在
