Localization system for interventional instruments
WO 2008129510 A3
The invention relates to a localization system that can be used for example in invasive interventions for determining the position of a catheter (2) such that this position can be mapped onto a previously acquired image (22) of the examined body region. The system comprises a transmitter (TX) that can be attached to the instrument to be located and that emits electromagnetic localization signals (S). Moreover, it comprises receivers (RX1, RX2, RX3) disposed at different known locations that pickup the localization signals outside the patient body. An evaluation unit (10) can then infer the spatial position of the transmitter (TX) from the measured arrival times of the localization signal at the different receivers (RX1, RX2, RX3).
