Abstract
A catheter localization 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 may be determined. The catheter localization system includes a catheter having a catheter head which is arranged in use to be conveyed through the human or animal body to a desired localization, a plurality of acoustic transducers disposed about said catheter head at predetermined localizations and a signal processing unit which operates 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 acting as acoustic receivers, which acoustic signals were generated by at least one of said plurality of acoustic transducers acting as an acoustic source.
