Summary:The embodiment of the invention relates to a cooling arrangement for a superconducting magnet structure for an MRI system. The superconducting magnet structure comprises a number of axially aligned superconducting inner magnet coils (34) making up an inner magnet structure (30) and a number of superconducting outer coils (32) each having an inner diameter greater than an outer diameter of each ofthe inner magnet coils (34). The inner magnet structure is enclosed within a cryogen vessel (12), and the outer coils are located outside of the cryogen vessel, in thermal contact with the cooling arrangement (36, 38) for cooling the outer coils. 本公开的实施例涉及用于MRI系统的超导磁体结构的冷却装置。本公开的实施例提供了种超导磁体结构，包括构成内部磁体结构(30)的多个轴向对准的超导内部磁体线圈(34)，以及多个超导外部线圈(32)，每个超导外部线圈具有比每个内部磁体线圈(34)的外直径更大的内直径。内部磁体结构封装在冷冻剂容器(12)内，并且外部线圈位于冷冻剂容器外部，与用于冷却外部线圈的冷却装置(36，38)热接触。
