Further system characterization of the single-sided mpi scanner with two-and three-dimensional measurements

With the single-sided MPI-Scanner unlimited object sizes can be measured and it is suitable for various medical applications. In previous measurements, the penetration depth for two-dimensional measurements has already been investigated, as well as the local resolution. The system has evolved from a one-dimensional to a three-dimensional system. Here, further measurements are carried out to characterize the system. To measure the penetration depth and spatial resolution as well as the influence of the orientation of the receiving coils, a four-layer phantom was measured three-dimensionally at different angles. Furthermore, a dilution series was measured to determine the linearity of the system reaction, which is a prerequisite for the quantifiability of the results. The results of both studies are shown and discussed in this work.
