MAGNETIC FIELD GENERATOR FOR MRI, PACKING MEMBER FOR THE SAME, AND METHOD FOR PACKING THE SAME |
摘要 |
A magnetic field generator for an MRI includes a generator main body. The generator main body includes a hair of plate yokes opposed to each other with space in between, a permanent magnet disposed in each of the opposed surfaces of the plate yokes, and a column yoke for magnetically connecting the plate yokes. As a packing member, a shielding member, and if necessary, a stud pin as well as a fixing member are prepared. When packing, the shielding member is attached to the generator main body for shielding an opening. The stud pin may be used for providing a gap between the generator main body and the shielding member. For an open-type generator, the fixing member should preferably be attached to bridge the pair of plate yokes at a middle portion of the opening.
