Patent ID: 8442625

Claim:
A system for position sensing and map generating, comprising: a mapping instrument having a position element and operable to be located in a volume; a least a first pair of axis generation electrodes positionable on a surface of the volume; a driver operable to inject a current between the first pair of axis generation electrodes to generate an axis current within the volume; a processor operable to determine a position of the mapping instrument and at least a pseudo position of the at least first pair of axis generation electrodes; a storage system operable to store the determined position of the mapping instrument; a display device configured to display a representation of the determined position of the mapping instrument and an icon representing the pseudo position of the at least first pair of axis generation electrodes based on the determined position of the position element of the mapping instrument due to the injected current from the at least first pair of axis generation electrodes on the display device relative to the determined position of the mapping instrument.
