ABSTRACT:
In a method and apparatus for determining the position of a catheter inside the body of a patient, position signals are transmitted between the catheter and a position location unit, located at a distance from the catheter, the position signals are transmitted during a calibration stage from known calibration positions inside the body, or position signals, transmitted by the position location unit, are received at the known calibration positions. A correction function is determined from the difference between the calibration positions derived from the received location signals and the known, true calibration positions, whereupon catheter positions, derived from received position signals, are corrected in subsequent measurement stages according to the correction function.
