Abstract

A method based on computed-tomographic reconstruction was developed to determine three-dimensional locations of electrodes on a concentric pair of a cylindrical probe and a basket-shaped catheter deployed in the intact canine left ventricle. The reconstructed geometric model was validated by assessing the quality of the solution to the forward problem relating endocardial potentials to probe potentials
