Abstract

An attack on background effects which degrade dose efficiency may be made by up to four moving slits installed in a diagnostic image intensifier system. These background effects are scatter, off-focal radiation, and intensifier glare. A version of slit radiography con-sisting of sectors rotating about the central ray of the x-ray tube is studied. Experiments are performed which evaluate the feasibility of this method. System options and trade-offs are discussed.
