Abstract
The gantry of a magnetic resonance imaging apparatus includes a static magnetic field magnet, a gradient coil, a high-frequency coil, and a sealed vessel housing the gradient coil. The sealed vessel is made of a nonconductive material. Even if a gradient magnetic field is switched at high speed, no eddy current flows in the sealed vessel. Therefore, the sealed vessel does not vibrate.
