Abstract
A system for determining the disposition of a probe within the body of a patient includes a probe having probe field transducers and one or more reference field transducers. The reference field transducers are affixed to a rigid but repositionable frame constructed to allow the transducers to be positioned in close proximity to the body. Non-ionizing fields are transmitted and detected between the probe and reference field transducers, and from the detected fields the relative disposition of the probe with respect to the reference field transducers is determined.
