Method for adjusting magnetic resonance imaging apparatus and superconductive magnet excitation dock

An adjustment method of a magnetic resonance imaging apparatus including a superconducting magnet, comprising:

• a training step of performing training for releasing distortion occurring in a superconducting coil by transporting a superconducting magnet manufactured in advance to a facility for excitation different from a facility where the superconducting magnet is to be installed and temporarily installing the superconducting magnet, cooling the superconducting coil of the superconducting magnet with a refrigerant, and supplying a current from an external power supply;
• a demagnetization and transportation step of demagnetizing the superconducting coil after the training as a preliminary step 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.

A dock for superconducting magnet excitation comprising:

• a plant for condensing helium gas to liquid helium;
• a frame on which a superconducting magnet is mounted;
• a supply pipe used to send liquid helium from the plant to the superconducting magnet;
• a recovery pipe used to send helium gas from the superconducting magnet to the plant;
• a power supply for supplying an excitation current to the superconducting magnet;
• and
• a power lead which connects the power supply to the superconducting magnet.
