ABSTRACT:
The invention relates to a magnet coil arrangement for generating linear magnetic gradient fields by means of which a three-dimensional spin density distribution of a body can be reconstructed (spin imaging). The magnet coil arrangement inter alia consists of a plurality of groups of single coils which are each time situated on an imaginary cylinder surface and which produce a magnetic field gradient in the interior of the cylinder which is constant over a larger range with respect to known magnetic coil arrangements. The magnetic coil arrangement also comprise four single coils which are situated on an imaginary spherical surface and wherethrough the same current flows for generating a constant field gradient which extends rotation-symmetrically with respect to an axis of examination.
