Abstract
In one embodiment, a magnetic resonance apparatus includes a gradient coil configured to be cylindrically-shaped and to apply a gradient magnetic field to a hollow region into which an object is inserted, the hollow region being formed, the hollow region being formed inside the gradient coil; and an RF coil configured to include a resonance circuit whose plural connecting conductors are folded back at one end side of the gradient coil so that the resonance circuit extends from the hollow region to an outer region of the gradient coil.

A magnetic resonance imaging apparatus comprising:
- a gradient coil configured to be cylindrically-shaped and to apply a gradient magnetic field to a hollow region into which an object is inserted, the hollow region being formed inside the gradient coil;
- and
- an RF coil configured to include a resonance circuit whose plural connecting conductors are folded back at one end side of the gradient coil so that the resonance circuit extends from the hollow region to an outer region of the gradient coil.
A coil device comprising:
- a local gradient coil configured to be arranged inside cylindrical structure in which a static magnetic field magnet, a whole-body gradient coil, and a whole-body RF coil are included and to apply a local gradient magnetic field inside the cylindrical structure;
- and
- a local RF coil configured to
- (a) include a resonance circuit whose plural connecting conductors are folded back at one end side of the local gradient coil so that the resonance circuit extends from a hollow region inside the local gradient coil to an outer region of the local gradient coil, and
- (b) be integrated with the local gradient coil.
