Gradient coils apparatus and method of the production of a gradient coil to artif file in images of an mr - imaging device to reduce

摘要

A gradient coil (300) or another element of a magnetic resonance - imaging device contains at least one layer (302), the copper with a first surface (316) and a second surface (318) comprises. A first semiconductor layer (314) is placed on a first surface (316) of the copper (302) and an insulation layer is applied is made to the second semiconductor layer (314, 414), the any voids or cavities or impurities, the between the copper (302) and the semiconductor layers (314, 414) are formed, the potential of which is similar to that of the voids, and prevents the formation of a partial discharge.
