Spatial encoding in magnetic particle imaging (MPI) is achieved by moving a field-free point (FFP) through the imaging volume. Recently, it was shown that the sensitivity of MPI can be increased by taking advantage of a field-free line (FFL) for spatial encoding. However, until today the power loss of an FFL scanner was thousand times higher than the power loss of an FFP scanner. In this work, the first feasible coil setup is presented, which has a power loss of the same order as an FFP scanner.
