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.
