    摘要： A local or surface coil including a decoupling circuit to allow the coil to operate as a receive-only coil in a host MRI system, in which case the system body coil typically provides the transmit signal. Further, the local or surface coil includes a circuit to defeat the decoupling circuitry for both low power [receive] and high power [transmit] functions to allow the same physical coil to be used as a transmit/receive coil in addition to a receive-only coil. The two modes of the coil allow the user to select the mode of local or surface coil operation best suited to the particular type of imaging being performed.
