摘要：

A gradient system according to the invention generates three superimposed gradient fields of which at least one of the three gradient fields is not unique in space (i.e. not bijective) and at least one of the three gradient has areas of the same field strength, which extend in parallel or orthogonally to a approximately U-shaped center plane of the teeth of one jaw of a patient.
