Abstract
The MRI apparatus has ring-shaped superconducting coils arranged to vertically oppose each other. The superconducting coils are installed in ring-shaped cooling containers. The cooling containers are accommodated in radiation shield plates. The radiation shield plates are accommodated in vacuum vessels. The cooling containers are connected together at at least two locations. Support members are arranged between an outer wall surface of the lower cooling container and an inner wall surface of the lower vacuum vessel to support the lower cooling container on the lower vacuum vessel. The upper cooling container is free, supported only by the connecting tubes connecting the upper and lower cooling containers.
