Adjustment methods and superconducting magnet excitation dock of the superconducting magnet for use in magnetic resonance imaging apparatus

摘要

An adjustment method of a magnetic resonance imaging apparatus includes: a cooling and excitation step in which work of transporting a superconducting magnet to a facility different from a facility where the superconducting magnet is to be installed, cooling a superconducting coil of the superconducting magnet with a refrigerant, and supplying a current from an external power supply for excitation is repeated until a predetermined rated current flows; a demagnetization and transportation step of demagnetizing the superconducting coil and transporting the superconducting magnet to the facility where the superconducting magnet is to be installed in a state where the superconducting coil is cooled by the refrigerant; and an installation step of installing the superconducting magnet in the facility where the superconducting magnet is to be installed and supplying a predetermined rated current from an external power supply to the superconducting coil in order to excite the superconducting coil.
