Method and system for monitoring separation between an electrode and a target point

An apparatus (20) for monitoring a distance between a probe electrode (22) and a target point comprises the probe electrode (22) and a receiving electrode (30) suitable for being positioned relative to the target point such that, in use, current may be driven between the probe electrode (22) and the receiving electrode (30) via the target point. The apparatus (20) further comprises an impedance measuring device (27) coupled to the probe electrode (22) and to the receiving electrode (30); and a processor (40) coupled to the impedance measuring device (27). The processor (40) is configured for receiving at least three probe electrode – receiving electrode impedance measurements for at least three different probe electrode – target point distances, and for determining from the at least three impedance measurements whether a stationary point exists in the impedance. A corresponding method is also provided.
