The Reconstruction of Three-Dimensional Obects from Two Orthogonal Projections and its Application to Cardiac Cineangiography

A method is developed for the reconstruction of a two- dimensional convex symmetric object from two orthogonal projections. To reconstruct a three-dimensional object, the object is divided into thin slices and the slices are individually reconstructed. An experimental result of the reconstruction of a clay model from its X-ray pictures is described. Applicability of this technique to cardiac cineangiography is discussed.
