Abstract
A catheter localization system for determining a position of a catheter (1, 2) within a part of the human or animal body (3), comprising at least one catheter (1, 2) having a plurality of acoustic transducers (6) disposed on the catheter in a spaced apart relationship. Each acoustic transducer (6) is arranged to transmit or receive acoustic signals (12, 14). A signal processing unit (8) is coupled to the plurality of acoustic transducers (6) and arranged to selectively energize the transducers (6) and consequent upon acoustic signals (12, 14) received by the acoustic transducers (6) generate a plurality of acoustic transfer functions (24, 28) representative of an effect of the part of the body on the acoustic signals, which signal processing unit (8) further operates to generate data appertaining to a three dimensional representation (36) of the part (4) of the human body (3) in accordance with the plurality of transfer functions.
