Abstract: Disclosed herein is a nano-magnetic-particle-imaging apparatus, including a measurement head including excitation and detection coils and accommodating a sample bed for a sample including nano magnetic particles; a gradient magnetic field generation unit for generating a magnetic field having a strength equal to or greater than that of the saturation magnetic field of the nano magnetic particles in a spacing area between identical magnetic poles facing each other and forming a field-free region in a portion thereof; a first driving unit for linearly moving the sample bed; a second driving unit for rotating the gradient magnetic field generation unit in a plane; a third driving unit for linearly reciprocating the gradient magnetic field generation unit; and a control unit for applying a signal to the excitation coil, controlling the driving units, and imaging 3D distribution of the nano magnetic particles based on a detection signal output from the detection coil.
