Claim 4:
5. The handheld MPI system based on FFL rotation according to claim 1, wherein the reception coil and the compensation coil of the detection module are symmetrically distributed inside the excitation coil;
the reception coil is located at a lower end of the detection module; and a bottom surface of the reception coil is coplanar with a bottom surface of the excitation coil to receive an excitation response signal of the magnetic particles; and
the compensation coil is located at an upper end of the detection module and has a winding direction opposite to a winding direction of the reception coil; and an upper surface of the compensation coil is coplanar with an upper surface of the excitation coil to counteract an excitation signal directly induced by the reception coil.
