摘要： A method of forming a shimming body for a NMR assembly is provided. A magnetizable metal powder of known magnetic properties is provided. The powder is uniformly dispersed into a non-magnetic material to form a mixture having a selected uniform density. A selected weight of magnetic material is determined for a particular installation of an NMR assembly. The mixture is heated. A selected volume corresponding to the selected weight of magnetic material is extruded into a container. The mixture is cooled to form a shimming body.
