Abstract
In a coil arrangement for nuclear magnetic resonance comprising a main coil (), a shielding coil (), and at least one correction coil (), the function of which consists in forming a magnetic field gradient with eddy current properties which are as good as possible, the main coil () and the shielding coil () are electrically connected in series with the correction coil (). The deviations of the residual field from the desired design generated by production tolerances are thereby modified by the correction coil in such a fashion that the long-lasting eddy currents are suppressed. This either reduces the waiting time that must lapse after a gradient pulse before a predetermined field homogeneity is achieved or e.g. the deviations from the desired field are minimized in imaging applications.
