Abstract
A magnetic resonance apparatus has a gradient coil system that includes a gradient coil arrangement with a conductor and magnetostrictive material, and contains a basic field magnet system for generating a basic magnetic field. The magnetostrictive material is thereby arranged in the immediate proximity of the conductor in regions having the same course as a course of the conductor, to suppress noise-producing vibrations.
Claims7
A magnetic resonance apparatus comprising:
- a basic field magnet system which generates a basic magnetic field;
- a gradient coil system having a gradient coil arrangement formed by at least one conductor in which current flows, said conductor following a conductor path to form a gradient coil in said gradient coil arrangement;
- and
- said gradient coil system further comprising magnetostrictive material disposed in immediate proximity to said conductor in regions following said conductor path to reduce noise produced by vibrations caused by Lorentz forces arising when current flows in said conductor in said basic magnetic field.
