An important requirement for a gradient coil is that the uniformity of the generated magnetic field gradient should be maximal within the active volume of the coil. For a cylindrical geometry, the radial uniformity of the gradient turns critic, particularly in cases where the gradient-unit has to be designed to fit into the inner bore of a compact magnet of(More)
—We discuss the problem of automatic magnetic field compensation within an excluded volume where the magnetic field cannot be sensed in a direct way. Both magnetic field spatial average (shielding) and first order orthogonal gradients (shim-ming) are considered. The active shielding-shimming compensator is based on a multiple-input multiple-output(More)
Spin-lock adiabatic field cycling imaging (SLOAFI) relaxometry was shown to be a useful technique for obtaining a fast study of spin-lattice relaxation dispersion in the rotating frame. The aim of the present article is to describe some technical aspects of the experiment in more detail, while showing simple examples that can be compared with laboratory(More)
