Abstract
In a method for operating a magnetic resonance apparatus, and a magnetic resonance apparatus for implementing the method, the magnetic resonance apparatus having a gradient system containing at least one gradient coil for generating a gradient field at least within an imaging volume, and at least one shield coil operable independently of the gradient coil for generating a shielding field with which the gradient field can be neutralized in a prescribable region, the gradient system is operated in an operating mode wherein the shield coil is operated for intensifying the gradient field within the imaging volume.
Claims30
A method for operating a magnetic resonance apparatus comprising the steps of:
- providing a gradient system having at least one gradient coil operable for generating a gradient field at least within an imaging volume, and at least one shield coil operable independently of said gradient coil, said shield coil being available for generating a shielding field for neutralizing said gradient field in a prescribable region;
- and
- operating said gradient system in an operating mode including operating said gradient coil to generate said gradient field at least within said imaging volume and operating said shield coil to intensify said gradient field within said imaging volume.
A magnetic resonance apparatus comprising:
- a gradient coil operable for generating a gradient field within an imaging volume;
- a shield coil operable to generate a shielding field which neutralizes said gradient field in a prescribable region;
- and
- a gradient amplifier and control unit connected to said gradient coil and to said shield coil for operating said gradient coil and said shield coil in an operating mode wherein said gradient coil generates said gradient field and wherein said shield coil intensifies said gradient field within said imaging volume.
