The single-sided scanner configuration is one of the most recent developments in the field of magnetic particle imaging (MPI). The main difference between the single-sided and the conventional symmetric configurations is in the co-planar topology of the selection coils in the former type. Although it is challenging to create high-strength gradients with a uniform field in the single-sided configuration, such a device provides the benefit of imaging of the near-surface regions of large objects that cannot be accommodated by the symmetric configuration. Current state-of-the-art single-sided scanners utilize a field-free point selection field. Previously, we presented a concept of a single-sided device based on a field-free line with permanent magnet (PM) selection coils. Here, we report on the progress of the development of a single-sided field-free line MPI scanner with PM selection coils, which are capable of producing a strong field gradient of G=3 T/m at a height of 3 cm above the surface.
