Abstract: The present disclosure relates to a magnetic particle imaging device having a field of view (FOV) wide enough to be applicable to the human body. A magnetic particle imaging device according to some embodiments includes at least: an FFP generation unit generating a field free point (FFP) in a FOV; first to third operation coil units moving the FFP in first to third directions which are vertical to each other, respectively; an excitation coil unit generating a magnetic field in the FOV, and exciting a magnetic particle in the FOV; a reception coil unit receiving a magnetic signal generated from the magnetic particle; and a processor dividing the FOV into a plurality of partial FOVs, controlling the first to third operation coil units so that the FFP moves in each partial FOV, and generating an image for the FOV based on the magnetic signal for each partial FOV.
