Gradient coil arrangement

摘要

The invention relates to a gradient coil arrangement for the generation of a gradient magnetic field for an MR arrangement with at least two gradient coils arranged on a cylinder surface with a substantially circular cross section. In order to enable adjustment of gradient fields extending as linearly as possible in the area of an object to be examined without having to modify the entire mechanical structure of the MR arrangement and without having to increase the power required to feed the gradient coil arrangement, it is proposed according to the invention to configure the gradient coils so as to be asymmetrical in relation to a central plane lying horizontally through the longitudinal axis of the cylinder.
