MAGNETIC RESONANCE IMAGING APPARATUS AND GRADIENT COIL

摘要

A magnetic resonance imaging apparatus according to an embodiment includes a static magnetic field magnet and a gradient coil. The static magnetic field magnet generates a static magnetic field. The gradient coil is provided on an inside of the static magnetic field magnet and includes an X coil, a Y coil and a Z coil. The X coil generates a gradient magnetic field along a horizontal axis of a substantially circular cylinder, the horizontal axis being perpendicular to a long axis. The Y coil generates a gradient magnetic field along a vertical axis of the substantially circular cylinder. The Z coil generates a gradient magnetic field along the long axis of the substantially circular cylinder. In the gradient coil, coils are laminated in such a manner that the X coil is positioned more distant from a magnetic field center than the Y coil is.
