摘要：

This paper describes an optimal design of a highly homogeneous resistive coil system for Magnetic Resonance Imaging (MRI). Magnetic material is used to improve field uniformity at the central region and to shield the magnet. The influence of magnetic material is calculated by using a code based on the solution of scalar and vector potentials equations. The obtained result is an axisymmetric coil configuration enveloped by iron whose optimization was made by fixing one of the criteria : the weak stray field near the magnet. It presents a great accessibility to the homogeneous area and satisfies the bore's required dimensions. Dimensions and field charts are given.
