The invention provides a method for reducing the vortex due to gradient magnetic field, for reducing the generation of vortex due to gradient magnetic field using anti-vortex apparatus in magnetic resonance system, wherein the said anti-vortex apparatus is formed by overlaying the metal laminates. The said method comprises: calculating the distribution of main field of magnetic resonance system in anti-vortex apparatus; calculating the distribution of the main field and gradient magnetic field in anti-vortex apparatus; subtracting the two distribution in magnetic field to obtain the distribution of the gradient magnetic field in anti-vortex apparatus; and adjusting the setup of metal laminates to reduce vortex based on distribution of the gradient magnetic field in anti-vortex apparatus. The gradient magnetic field is parallel with or basically parallel with the plane of the metal laminates after adjusting the metal laminates of anti-vortex apparatus. Furthermore, the metal laminates are ...

The invention provides a current lead wire for a superconducting magnet of a magnetic resonance system, wherein, the superconducting magnet is refrigerated by a cold head. The invention comprises a current lead wire anode and a current lead wire cathode which are electrically connected with the superconducting magnet for excitation, wherein, the cold head is electrically connected with the superconducting magnet and used as the current lead wire anode or the current lead wire cathode. The invention utilizes the cold head to be as the current lead wire anode or the current lead wire cathode, thereby the number of current lead wires and the heat which is conducted through the current lead wires are reduced, consequently a stable superconducting environment can be more efficiently maintained. Moreover, the cold head and the current lead wires of the invention can be arranged inside the same pipe, thereby a tower pipe and a side pipe are unnecessary to be separately designed, consequentlythe ...
