1. Apparatus for the determination of the respective position of the front end of a probe inserted into a living body, comprising a transmitter, which is movable outside the body and is producing electromagnetic waves, and a receiver attached to the probe containing a sensor which reacts on the field intensity of the waves of the transmitter received by the receiver, and of which the optical and/or acoustical indication is a function of the respective field intensity at the receiver, characterized in that the receiver (5) is connected to a filamentary receiving antenna which extends from the part of the probe (3) being outside the body (2) to the front end (3A) of this probe. |
