In a signal receiving method and device for a magnetic resonance imaging system, a first loop receiver coil has a saddle receiver coil overlapped thereon, and two individual loop receiver coils or two counter rotating loop receiver coils connected end-to-end are equally spaced from the first loop receiver coil along the axial direction of the first loop receiver coil, forming a dual-loop receiver coil unit. Thus, the magnetic resonance signal generated by human tissue induces current on the dual-loop receiver coil unit following excitation of the signal. When the device is operated, the signal current induced in the saddle receiver coil, the first loop receiver coil and the dual-loop receiver coil unit respectively are added, thus increasing the output signal-to-noise ratio, improving the edge imaging effect, increasing the coverage of the coil signal and improving the signal homogeneity in the imaging area.
