Summary:The invention relates to a low-cost mobile ultralow-field nuclear magnetic resonance imaging device, and belongs to the technical field of medical electromagnetic detection. The device comprises a spoke-shaped magnet, a gradient coil, a shimming coil and a radio frequency coil. Wherein the spoke-shaped magnet comprises an upper magnet ring and a lower magnet ring, and can also be in the form of an upper magnet ring group and a lower magnet ring group; the gradient coils are three groups of biplanar coils, the gradient magnetic field direction is the same as the main magnetic field direction, and the gradient coils are superposed on the main magnetic field to realize space imaging coding; each group of shimming coils counteracts one harmonic magnetic field of the main magnetic field; the radio frequency coil is a transmit-receive integrated solenoid coil, generates a radio frequency excitation magnetic field in a time-sharing manner, and receives a magnetic resonance signal. The device is simple in structure,
