Abstract
A process of determining the three-dimensional location of a pacemaker lead in the heart of a subject is provided. The process includes the steps of acquiring a plurality of two-dimensional images of the lead; calculating the imaging geometry; identifying the two-dimensional position of the lead in each of the images; temporally interpolating the identified two-dimensional positions to identify a two-dimensional position of image at a single time; and calculating the three dimensional location of the lead from the two-dimensional position at that time.
