Abstract
A system for the generation of magnetic gradient fields which intermittently overlap the static magnetic field of a nuclear-spin tomograph, with at least one pair of gradient coils, powered from a power supply, through which current flows in series when in operation and which generate, in a predefined volume under examination, a gradient magnetic field that varies at least approximately in linear fashion with position in one direction, is characterized in that each gradient coil (A, B) has one set with at least one first winding zone (S1) and one set with at least one second winding zone (S2), which have terminals (16, 17; 18, 19) that are separate from one another, in such a way that the winding zones can be easily be connected to and separated from one another in varying ways. The user can thereby modify the properties of the gradient system.
