Abstract:
1. An adjustment method of a magnetic resonance imaging apparatus including a superconducting magnet, comprising: a cooling and excitation step of after transporting the superconducting magnet manufactured in advance to a work site facility for excitation different than a permanent facility where the superconducting magnet is to be installed, temporarily installing the superconducting magnet at the work site facility and cooling a superconducting coil of the superconducting magnet with a refrigerant, wherein at the work site facility 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 excited by the rated current as a preliminary step and transporting the superconducting magnet from the work site facility to the permanent 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 permanent 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.
