Mri apparatus

Abstract

In one embodiment, an MRI apparatus includes: a cylindrical static magnetic field magnet; a cylindrical gradient coil; a vibration isolator; and processing circuitry. The cylindrical static magnetic field magnet is configured to generate a static magnetic field. The cylindrical gradient coil is installed inside the static magnetic field magnet. The cylindrical gradient coil is configured to generate a gradient magnetic field. The vibration isolator is disposed between the static magnetic field magnet and the gradient coil. The vibration isolator includes a plurality of vibration-proof materials provided in a circumferential direction of a cylindrical body of the static magnetic field magnet and in a height direction of the cylindrical body, each of the vibration-proof materials being composed of a pair of a spring and a damper. The processing circuitry is configured to control springs and dampers constituting the plurality of vibration-proof materials according to a type of pulse sequence.
