A magnet design strategy is proposed, starting from a three-dimensional finite configuration that completely confines the field and that contains a closed cavity where the field is perfectly homogeneous. When the cavity is opened on one or more sides to allow patient access distortions are induced and a stray field arises, but the three-dimensional starting point introduces a new degree of freedom that would be otherwise absent
