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.},
