Abstract
In a diagnostic nuclear magnetic resonance apparatus having a main magnetic field and gradient coils for generating gradient fields, the gradient coils including conductors that run essentially perpendicularly to the direction of the main magnetic field, compensating coils for reducing the main magnetic field present in the environment of the conductors are allocated to these conductors. By reducing the effect of the main magnetic field in regions near these conductors, oscillations of these conductors arising due to switching of the gradient current are reduced, thereby reducing bothersome noises which arise during the production of an image.
