More Information
Summary:The utility model discloses a magnet apparatus using for magnetic resonance imaging systems, comprising two groups of permanent magnetism magnetic bodies, two groups of circular pole plates, a dredging magnetic yoke, and a connecting magnetic yoke. The poles of the two groups of permanent magnetism magnetic bodies are in corresponding arrangement to form an N-S and N-S shape, and a gap space is arranged in the middle part. A center height surface is a symmetry surface. The magnetic bodies and the pole plates are in symmetric distribution up and down. The pole plate comprises a pole plate body and a uniform-field ring. The center of the pole plate is provided with a hollow part. The place corresponding to the hollow part is provided with a ferromagnetic slide block which moves up and down. The utility model forms a strong and stable uniform magnetic field in larger space.
