More Information
Summary:A magnet assembly for use in a magnetic resonance imaging system includes an outer cylindrical casing composed of a plurality of axially separate, connectable cylinder blocks, a plurality of air core coils arrayed in each of the cylinder blocks for generating a static magnetic field, a plurality of bases supporting each of the cylinder blocks, two discs attached respectively to axially opposite ends of the outer cylindrical casing, a plurality of three-dimensional adjustment bolts mechanisms disposed in the cylinder blocks and on the discs and having bolts hend endwise against the air core coils for positionally adjusting the coils independently in three directions with respect to axes of the cylinder blocks, and a plurality of connectors interconnecting the cylinder blocks into the outer cylindrical casing.
