Abstract
A high-performance magnet generating a homogeneous field contributes significantly to the quality of magnetic resonance imaging (MRI), and permanent-magnet assemblies, which can be specially configured for the particular whole body, pediatric, or orthopedic use, unlike superconducting and resistive magnets, help to ensure homogeneity. The paper surveys the suitability of tunnel-like, ordinary, and elliptic-cylinder-like configurations of permanent magnets in these uses
