Abstract:
A gradient coil arrangement for a magnetic resonance tomography apparatus, comprising:a first set of windings comprising a plurality of individual windings disposed in at least a primary winding surface;a second set of windings comprising a plurality of individual windings disposed in a secondary winding surface, said primary winding surface and said secondary winding surface being radially spaced from each other;said primary winding surface and said secondary winding surface having an end face, and each of said individual windings in said first set of windings and each of said individual windings in said second set of windings having free conductor ends at said end face;a plurality of connector elements for selectively connecting said free conductor ends in said primary winding surface to said free conductor ends in said secondary winding surface and for connecting free conductor ends within said primary winding surface to other free conductor ends within said primary winding surface and for connecting free conductor ends in said secondary winding surface to other free conductor ends in said secondary winding surface; andsaid connector elements being selectively connectable and disconnectable to said free conductor ends to switchably form a plurality of different combinations of individual windings in said first set of windings and individual windings in said second set of windings to form different gradient coil arrangements respectively having different field qualities and performance features.
