Abstract
In order to produce field strength gradients (x,y) for a NMR machine, the curve-shaped gradients are substituted by coils arraigned in tubes. Said tubes are distributed on the annular circumference () of the examination space of the tunnel NMR machine. Said invention makes it possible to produce at request field strength gradients in all necessary directions by providing each tube with the same set of coil elements and supplying them with selected currents.
