Shim support guide jig for magnetic field generation apparatus, magnetic field generation apparatus and magnetic resonance imaging equipment each including shim support in which magnetic material shims are arranged and adjusted by employing shim support guide jig, and magnetic field adjustment method for magnetic field generation apparatus, as well as magnetic field adjustment method for magnetic resonance imaging equipment

摘要

A shim support guide jig includes a shim support guide pipe in which a guide passage for guiding the movement of a shim support is formed. In a state where a superconducting magnet has generated a static magnetic field, the designated shim support can be drawn out from the internal space of the superconducting magnet through the guide passage, and the designated shim support for which magnetic material shims have been arranged and adjusted can be inserted into the internal space through the guide passage. A magnetic field generation apparatus has the magnetic material shims arranged and adjusted using the shim support guide jig, and a magnetic resonance imaging equipment employs the magnetic field generation apparatus. Magnetic field adjustment methods for the magnetic field generation apparatus and for the magnetic resonance imaging equipment are performed using the shim support guide jig.
