Abstract
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.
