1. A magnetic particle imaging system that images magnetic particles in a field free region using an excited magnetic field for the magnetic particles, the magnetic particle imaging system comprising:
a field free region generator to generate a field free line with a direction of linear extension of the field free region as a direction of extension; and
an excited magnetic field generator to generate the excited magnetic field in the field free line generated by the field free region generator, wherein
the excited magnetic field generator includes a first excited magnetic field generation unit and a second excited magnetic field generation unit, and
the first excited magnetic field generation unit and the second excited magnetic field generation unit are spaced from each other in the direction of extension of the field free line.
