A method of determining the position of an induction-susceptive device inside an anatomical body part, comprises the following steps: a) emitting, towards the anatomical body part and from an electromagnetic emitter device, an oscillating electromagnetic field having a predetermined first field strength; b) acquiring, by using an electromagnetic detector device, an electromagnetic detection signal describing a second field strength which corresponds to the field strength of the electromagnetic field in the proximity of the anatomical body part; c) determining, based on comparing the first field strength and the second field strength, whether the second field strength differs from the first field strength, and d) if the second field strength differs from the first field strength, issuing a corresponding position indicating signal from an indication device, which position indicating signal indicates the presence of the induction-susceptible device. |
