Patent ID: 7633292

Claim:
A method for reducing eddy currents caused by a gradient magnetic field in a magnetic resonance system in which a basic magnetic field is generated, said method comprising the steps of: providing an anti-eddy current device in the magnetic resonance system that reduces eddy currents in the magnetic resonance system caused by the gradient magnetic field, said anti-eddy current device comprising a plurality of settable laminated metallic plates; automatically electronically calculating a distribution of the basic magnetic field in the anti-eddy current device; automatically electronically calculating the distribution of the basic magnetic field and the gradient magnetic field in the anti-eddy current device; automatically electronically subtracting the calculated distribution of the basic magnetic field in the anti-eddy current device from the calculated distribution of the basic magnetic field and the gradient magnetic field in the anti-eddy current device, to obtain a distribution of the gradient magnetic field in the anti-eddy current device; and adjusting a setting of the metallic plates in the anti-eddy current device dependent on the distribution of the gradient magnetic field in the anti-eddy current device to reduce said eddy currents produced in the magnetic resonance system by said gradient magnetic field.
