Magnetic Field Generation for Multi-Dimensional Single-Sided Magnetic Particle Imaging

Introduction: Magnetic particle imaging (MPI) is a method capable of determining the spatial distribution of super-paramagnetic iron oxide particles (SPIOs) at potentially high sensitivity, high spatial and high temporal resolution [1,2,3]. The feasibility of a single-sided coil arrangement for field generation and reception of the particle signal was shown in [4]. There, the object of interest is positioned in front of a scanner head and not inside a scanning chamber. Consequently, the total size of the object to be examined does not matter whereas the scannable field of view (FOV) is still limited. So far, applying the single-sided concept, a 1D-imaging device has been implemented [4] which allows only for scanning a single line in space. In this contribution, different coil arrangements are shown, which extend the existing setup towards 2D imaging.
