The modern angiographic laboratory should be equipped to perform peripheral, visceral, and interventional procedures. Biplane, magnification, multiangulation, and spot filming capabilities are all desirable. Power requirements have decreased in recent years as a result of the introduction of rare earth screen-film systems and the incorporation of carbon fiber into tabletops and film changer faceplates. As a result, generators with lower power outputs and x-ray tubes with smaller focal spots can be used. Multiangulation rotational mounting units have been developed in recent years by the major equipment manufacturers; these units have major advantages over older ones, but their designs incorporate certain drawbacks with which angiographers should be familiar.
