Patent number: 7852629Abstract: A suspension device mounts a superconducting magnet heat shield enclosure that encompasses a low-temperature container, that encompasses a superconducting magnet and holds coolant for cooling the superconducting magnet. The low-temperature container has an outer heat shield layer and an inner heat shield layer. A vacuum jacket encompasses the heat shield enclosure and has an outer vacuum shell and an inner vacuum shell. A first set of suspension parts connects the outer vacuum shell with the low-temperature container, and a second set of suspension parts connects the outer heat shield shell with the low-temperature container. Since the second set of suspension parts connect the heat shield enclosure directly with the low-temperature container, this reduces the relative movement between the two parts, thus alleviating the streaking phenomenon in a magnetic resonance image, if the superconducting magnet is part of a magnetic resonance imaging system.Type: GrantFiled: February 27, 2009Date of Patent: December 14, 2010Assignee: Siemens AktiengesellschaftInventor: Xing En Yu

Patent number: 7679365Abstract: A current lead for the superconducting magnet of a magnetic resonance system, the superconducting magnet being refrigerated by a cold head, has a positive current lead and a negative current lead electrically connected to the superconducting magnet for magnetization thereof. The cold head is electrically connected to the superconducting magnet and is used as one of the positive and negative current leads. The cold head is used as the positive current lead or the negative current lead so as to reduce the number of current leads as well as the heat conducted by the current lead, therefore it maintains a stable superconducting environment more efficiently. Furthermore, the cold head and the current lead can be provided in the same conduit without the need to design a separated turret tube and side tube, and the structure of the current leads of the superconducting magnet of the magnetic resonance system is simplified.Type: GrantFiled: January 30, 2008Date of Patent: March 16, 2010Assignee: Siemens AktiengesellschaftInventors: Xi Yang Du, Huai Yu Pan, Zhong You Ren, Xing En Yu
