An MPI device based on parallel scanning of multiple magnetic field free lines (FFLs) is provided. The MPI device includes a first coil, a second coil, an excitation coil, and a receiving coil; the first coil is configured to receive a first-frequency current and generate a plurality of FFLs; the second coil is configured to receive the first-frequency current and drive the FFLs to rotate under a joint action with the first coil; the excitation coil is configured to receive a second-frequency current and drive the FFLs to scan fast; the receiving coil receives a particle signal scanned by the FFLs at each time point; and the first coil, the second coil, the excitation coil and the receiving coil are provided in longitudinal symmetry along the center of the imaging field of view.
