Abstract

Methods and systems for position determination are described for using an intrabody probe having a plurality of electrodes to generate a plurality of different electrical fields, and to also measure, using the plurality of electrodes, a measurement set (a Ve-e measurement set) comprising a plurality of measurements of the plurality of different electrical fields while the probe remains in one position. From the Ve-e measurement set, spatial position coordinates for the intrabody probe are estimated within an intrabody coordinate system, using an established mapping between previously observed Ve-e measurement sets and positions in the intrabody coordinate system. Systems and methods for generating and selecting such mappings are also described.
