A system for one-sided measuring a presence of magnetic particles in a probe volume comprises a one-sided coil assembly and a current controller, wherein the one-sided coil assembly is arranged around a central coil assembly axis for generating a rotating magnetic field distribution and comprises at least 3, preferably at least 4, circumferentially distributed coil assembly sectors, wherein the current controller is configured to generate a time varying current in each of said coil assembly sectors, said time varying current comprising a periodic modulation with a rotation frequency and phase shifted between adjacent coil assembly sectors to generate a magnetic field rotating in a plane perpendicular to the coil assembly axis, said magnetic field rotating with a rotation frequency associated with a frequency of said periodic modulation, and wherein the system is configured for measuring said presence of magnetic particles in said probe volume with said one-sided coil assembly.

A system for generating a traveling field free line, traveling along a propagation direction different from the orientation of said traveling field free line, said system comprising at least a first and a second coil assembly, wherein said first coil assembly is configured for generating a first stationary field free line at a first location when a current is flowing in the first coil assembly and the second coil assembly is current free, and wherein said second coil assembly is configured for generating a second stationary field free line at a second location, when a current is flowing in the second coil assembly and the first coil assembly is current free. The system further comprises a controller configured for driving the first and second coil assemblies with corresponding driving currents synchronized with each other, such that said traveling field free line travels along the propagation direction from a first location towards a second location.
