    • A microwave ablation system includes a generator including a first energy source, a second energy source and a diplexer, the diplexer multiplexes a first energy from the first energy source and a second energy from the second energy source. The system also includes a cable including a center conductor and an outer sheath where the multiplexed energy is transmitted through the center conductor. In addition an antenna is provided that is operable to receive the multiplexed energy from the center conductor and to deliver the multiplexed energy to a region of tissue. The outer sheath acts as a return path of the second energy to the second energy source. A sensor is also provided that measures at least one parameter of the second energy generated by the second energy source and the second energy returned from the region of tissue.
    • 微波消融系统包括包括第一能量源,第二能量源和双工器的发生器,所述双工器多路复用来自所述第一能量源的第一能量和来自所述第二能量源的第二能量。 该系统还包括一个包括中心导体和外护套的电缆,其中复用的能量通过中心导体传输。 此外,提供了一种天线,其可操作以从中心导体接收多路复用的能量并将多路复用的能量传送到组织区域。 外护套充当第二能量返回到第二能量源的路径。 还提供了一种传感器,其测量由第二能量源产生的第二能量和从组织区域返回的第二能量的至少一个参数。
