Abstract
A system for performing an invasive diagnostic or therapeutic medical procedure includes a first probe having a distal portion carrying a plurality of functional elements and a second probe having a distal portion carrying a functional element and a location sensor. The system includes a proximity processing subsystem in communication with the functional elements carried by each of the first and second probes and configured to determine a proximity of the functional element carried by the second probe relative to a first functional element carried by the first probe. The systems further includes a location processing subsystem configured to determine an absolute position and orientation of the location sensor carried by the second probe with respect to a three-dimensional reference coordinate system that can be internal or external to the three-dimensional space in which the first and second probes are positioned.
