Design for obtaining the half-axial projection

A simple, inexpensive technique to permit the half-axial projection in laboratories with single plane cineangiography

A simple inexpensive modification to permit x-ray beam angulation of a cineradiographic system consisting of a ceiling-suspended image intensifier and an under-the-table x-ray tube is described. This has permitted the incorporation of the half-axial projection into the routine evaluation of the proximal left anterior descending artery (LAD) with a minimum of patient discomfort.
