Abstract
A nuclear magnetic resonance tomography apparatus with a combined radio-frequency antenna and gradient coil structure has a gradient coil is divided onto at least two cylinder surfaces concentric with one another. Useful conductors of the gradient coil lie closer to the examination space than its connecting conductors. A radio-frequency antenna is built to the interspace between the inner useful conductors and the connecting conductors that lie farther toward the outside. The arrangement occupies less space in the magnet as a result of the combined structure.
