      abstract     = {We present two magnetic particle imaging (MPI) systems with
                      bore sizes of 75 mm and 100 mm, respectively, using
                      three-dimensionally arranged permanent magnets for
                      excitation and frequency mixing magnetic detection (FMMD)
                      coils for detection. A rotational and a translational stage
                      were combined to move the field free line (FFL) and acquire
                      the MPI signal, thereby enabling simultaneous overall
                      translation and rotational movement. With this concept, the
                      complex coil system used in many MPI systems, with its high
                      energy consumption to generate the drive field, can be
                      replaced. The characteristic signal of superparamagnetic
                      iron oxide (SPIO) nanoparticles wasgenerated via movement of
                      the FFL and acquired using the FMMD coil. The positions of
                      the stages and the occurrence of the f1 + 2f2 harmonics were
                      mapped to reconstruct the spatial location of the SPIO.
                      Image reconstruction was performed using Radon and inverse
                      Radon transformations. As a result, the presented method
                      based on mechanical movement of permanent magnets can be
                      used to measure the MPI, even for samples as large as 100
                      mm. Our research could pave the way for further
                      technological developments to make the equipment human size,
                      which is one of the ultimate goals of MPI.},
