A catheter tracking system as depicted in Figures 1,2, and 3 for locating and tracking a position of a catheter head 16 within a part of a human or animal bod y 1. The catheter tracking system comprising of a catheter 10 having a head 16 which is arranged to be conveyed through a human or animal body to a desired location, a plurality of magnetic field transducers, at least one of which is disposed on the catheter 18, and others of which are located in/or around a body and which serve as reference transducers 19, and a control unit which energises the plurality of magnetic field transducers. Upon processing of the magnetic fie ld signals the position of a catheter head 16 with respect to reference transducers 19 is determined. |
