The setup proposed here allows the concentric arrangement and individual rotation of four Halbach cylinders, whose purely mechanic agitation allows the movement of the field-free region through the field of view. Based on the requirements for such a rotation system, basic design approaches are presented and compared. Initial strength calculations and further simulations were performed on the resulting constructive concept, which, upon implementation, forms the basis for almost purely mechanical MPI scanners.en2365-903320221, Suppl 1Infinite Science Publishinghttps://creativecommons.org/licenses/by/4.0/InformatikMedizinJournal Article10.15480/882.441810.18416/ijmpi.2022.220306610.15480/882.4418Journal Article
