Original Abstract Submitted

A methods and systems are disclosed to determine positions of one or more distal end portions of a catheter. In embodiments, the method includes processing location signals that are transmitted by a transmitter-receiver utility having a first clock, and received by a position sensor at a catheter's distal-end portion. The processing may be performed by a signal processor having a second clock not synchronized with the first clock of the transmitter-receiver utility. The processing includes: determining a clock-rate-ratio between clock-rates of the first and second clocks; determining a time-lag between the first and second clocks; and determining the relative phases of the received signals while compensating for the clock-rate-ratio and for the time-lag between the clocks, such that determined phases are adjusted relative to the first signal clock of the transmitter receiver utility. Accordingly, the position of the catheter's distal-end portion can be determined based on the relative phases.
