Magnetic field generating device used for MRI.

摘要

A magnetic field generating device used for MRI having a pair of magnetic poles opposed to each other with a gap formed therebetween and generating a magnetic field in said gap, wherein the magnetic poles (10) formed by laminating and integrating a plurality of non-oriented silicon steel sheets (13) are disposed. The eddy current generated in the magnetic poles caused by the application of GC pulses can be reduced and the phenomenon of the residual magnetism can also be reduced. <IMAGE>
