Abstract

A gradient coil arrangement for a nuclear magnetic resonance tomography apparatus contains windings arranged in a primary winding plane as well as further windings arranged in a secondary winding plane. The primary and the secondary winding planes are radially spaced from each other thereby have a radial spacing. At an end face of the gradient coil arrangement, the windings have a number of open (free) conductor ends, and connector elements connect conductor ends in the primary winding plane to conductor ends in the secondary winding plane and/or connect conductor ends within one of the winding planes to one another. The connector elements are switchably fashioned for forming gradient coil arrangements having different field qualities/performance features.
