Abstract
Provided is an electromagnetic device for magnetic particle imaging, including: a return yoke having a gap, which extends in a Y direction and forms a magnetic field space; a gradient magnetic field generating unit, which is provided to the return yoke, and is configured to generate, in the magnetic field space, a gradient magnetic field in an X direction, and to form, in the magnetic field space, a zero-field region extending in the Y direction; an alternating magnetic field generating unit, which is provided to the return yoke, and is configured to generate an alternating magnetic field in the magnetic field space; and a rotation mechanism configured to rotate the gradient magnetic field and the alternating magnetic field relative to a subject with a Z direction being a rotation axis.
