超声换能器和位置传感器之间隔绝的导管
摘要：
本发明涉及超声换能器和位置传感器之间隔绝的导管。本发明公开了一种医疗设备，包括侵入式探针，所述侵入式探针用于插入活受试者体内。本发明公开了一种超声子系统，包括包含在所述探针内的超声换能器，和图像处理电路，所述图像处理电路设置在所述探针外部，并且被耦接以与所述探针内的所述超声换能器通讯。本发明公开了一种位置感测子系统，包括包含在所述探针内的位置换能器，和位置跟踪电路，所述位置跟踪电路设置在所述探针外部，并且被耦接以与所述位置换能器通讯，从而测定所述超声换能器在受试者身体内的位置坐标。所述位置感测系统与所述超声子系统电隔绝。
摘要（英）：

Medical apparatus includes an invasive probe, for insertion into a body of a living subject. An ultrasonic subsystem includes an ultrasonic transducer contained in the probe and image processing circuitry, which is located outside the probe and is coupled to communicate with the ultrasonic transducer in the probe. A position sensing subsystem includes a position transducer contained in the probe and position tracking circuitry, which is located outside the probe and is coupled to communicate with the position transducer so as to determine position coordinates of the ultrasonic transducer in the body. The position sensing subsystem is electrically isolated from the ultrasonic subsystem.
