A magnetic particle imaging (MPI) device based on an asymmetric bilateral structure includes a fixed section and a movable section. The fixed section includes a pair of magnetic field generation coils, and the magnetic field generation coils are configured to generate a uniform and variable magnetic field and drive a field-free point (FFP) to move along a Z-axis direction. The movable section includes a permanent magnet, excitation coils and a reception coil. The permanent magnet is configured to cooperate with the magnetic field generation coils to generate the FFP. The excitation coils are configured to move the FFP on a two-dimensional plane and excite magnetic particles to generate a nonlinear response signal. The reception coil is configured to receive an MPI signal. The MPI device is simple in structure and convenient to operate, and can perform targeted local imaging or covered overall imaging on the target object.
