Abstract
The invention relates to a process for manufacturing magnetic field generating devices in Nuclear Magnetic Resonance imaging apparatuses and to an image generating device according to said method. According to the invention, at least one layer of each pole piece is composed a plurality of adjacent or overlapping sheets, electrically insulated from each other. These sheets or foils may have slots, notches or apertures which cause bridges of a material having a lower electric conductivity to be formed between the areas separated by the notches and/or apertures. The bridges of material may be removed after sheet assembly by a cutting operation, particularly by laser cutting.
