CARDIAC CATHETER LOCALISATION SYSTEM

摘要

A catheter localisation system for generating information appertaining to a three dimensional map of a part of a human or animal body from which three dimensional map a position of said catheter (1) may be determined. The catheter localisation system comprises a catheter (1) having a catheter head (6) which is arranged in use to be conveyed through the human or animal body to a desired localisation, a plurality of acoustic transducers (8) disposed about said cathet er head (6) at predetermined localisations and a signal processing unit which opera tes to determine said three dimensional map of said part of a human or animal body consequent upon signals received by a plurality of acoustic transducers (8) acti ng as acoustic receivers, which acoustic signals were generated by at least one of said plurality of acoustic transducers acting as an acoustic source.
