摘要：
A system (10) for externally locating a sensor in tissue, comprising an external probe including at least first and second electromagnetic output coils (12) with non-parallel longitudinal axes; and output coil (2) driver for alternately energizing the first and second output coils, for generating a time-varying magnetic field which penetrates the patient's skin (7); a sensor coil (30), having a longitudinal axis, for developing an induced electrical voltage in response to the time-varying magnetic field; a distance determinator, responsive to the induced voltage from the sensor coil (30), for determining from the induced voltage, the distance between the output coils (12) and the sensor coil (30), independently of the relative angle, in a horizontal plane, between the sensor coil (30) longitudinal axis, and the longitudinal axes of the output coils (12); and a direction determinator for determining and displaying the direction, in the horizontal plane, in which the sensor coil (30) longitudinal axis is pointing.
