ABSTRACT:
A medical magnetic positioning system and method for determining the position of a magnetic probe inside a body of an individual in which at least two spaced magnetometers are fastened to an area on an external portion of an individual's body proximate to the desired location of the probe inside of the body, the magnetic probe is inserted inside the body of the individual to be spaced from the at least two magnetometers, the three-dimensional magnetic field of the probe is detected at the at least two magnetometers, and the location of the probe is determined in accordance with the location of the detected three-dimensional field. Preferably the magnetometers are triaxial magnetometers adapted to be mounted on an external portion of the body proximate to the inserted location of the probe so that the magnetometers measure the three-dimensional magnetic field of the probe. A computer is used for calculating and storing information relative to the position of said probe by using a non-linear computer algorithm.
