摘要： A debugging device for a body coil of a magnetic resonance imaging (MRI) system includes a pair of output ports connected to a pair of input ports of the body coil. The debugging device also includes a pair of input ports connected to a pair of output ports of the MRI system. The debugging device includes a pair of extension circuits, separately connected between the pair of input ports and the pair of output ports; and a first adjustment capacitor for reducing or eliminating coupling between the pair of input ports. The first adjustment capacitor is bridged between the pair of input ports, and the capacitance of the first adjustment capacitor is variable.
