Abstract
A method, and system for determining the position, and optionally, the orientation of a work piece such as a catheter within a cavity of an opaque body such as a patient. The position, and orientation are to be determined relative to a primary coordinate system, for example, the coordinate system of an imaging device. Using a primary reference transducer (210) that interacts with a primary field, and several secondary reference transducers (310) that interact with a secondary field, the coordinates of the secondary reference transducers are determined in the primary coordinate system.
