ABSTRACT:
The invention relates to a nuclear spin tomograph in which means for the homogenization of the normally present magnetic fields are provided. These means are formed by iron plates (24a, 26a, 28a), whose form, size, arrangement and number are chosen accordingly. The iron plates (24a, 26a, 28a) may be applied parallel to the longitudinal direction of the housing on the housing sides and in star form on one of the end walls (20) of the housing (23).
