Zusammenfassung: | The utility model relates to a shimming structure of magnetic resonance equipment, which is characterized in that central shimming structures are embedded at centers of upper pole magnetic steel and lower pole magnetic steel of a magnetic body of the magnetic resonance equipment, peripheral shimming structures are respectively arranged on the outer sides of peripheries of upper and lower pole heads at a 45+-5-degree angle, the peripheral shimming structures which can be one or two are arranged at an interval, the central shimming structures of the upper and lower poles are arranged symmetrically, and the peripheral shimming structures of the upper and lower pole heads are arranged symmetrically. The shimming structure is simple in structure, easy for installation and convenient for operation and training, shortens debugging time, reduces usage of samarium cobalt magnetic sheets greatly, saves debugging cost and increases magnet stability. |
