Abstract
A magnetic resonance imaging apparatus according to an embodiment includes a magnetostatic field magnet, a gradient coil, and a bore tube. The magnetostatic field magnet is formed to have a cylindrical shape. The gradient coil is formed to have a cylindrical shape, on the inside of the magnetostatic field magnet. The bore tube is formed to have a cylindrical shape, on the inside of the gradient coil. A first space between the gradient coil and the bore tube is configured to be kept in a vacuum state while a second space between the gradient coil and the magnetostatic field magnet is configured to be kept in a state not being a vacuum.

A magnetic resonance imaging apparatus comprising:
- a magnetostatic field magnet formed to have a cylindrical shape;
- a gradient coil formed to have a cylindrical shape, on an inside of the magnetostatic field magnet;
- a bore tube formed to have a cylindrical shape, on an inside of the gradient coil, and
- a hermetically-sealing member configured to hermetically seal a space between the gradient coil and the bore tube, wherein
- the hermetically-sealing member is an annular-shaped member that has a hollow inside and has a hole formed therein through which air is drawn into the hollow.
