摘要： The present invention relates to an MPI (Magnetic Particle Imaging) apparatus and a method for influencing and/or detecting magnetic particles in a field of view. Rather than moving the FFP (field free point) along a single, time-consuming high density trajectory it is proposed to use a number of low density trajectories with travelling phase, wherein each of said low density trajectories has the form of a closed curve differently located within the field of view.
