Abstract
Magnetic resonance apparatus includes an essentially cylindrical magnet system (2) for generating a steady magnetic field (H) in a measurement space (28), a coil system (4) for generating gradient fields in the measurement space, and at least one RF coil (10) which is arranged in the immediate vicinity of the measurement space. In order to increase the homogeneity of the main magnetic field (H), approximately annular first elements (44) of a magnetically conductive material are provided within the magnet system (2) so as to extend coaxially with respect to the axis (9) of the magnet system. In order to minimize the amount of magnetically conductive material required, the first elements (44) are situated in the immediate vicinity of the RF coil (10).
