ABSTRACT
The chest radiograph (CXR) remains the most widely used diagnostic imaging test for the evaluation of respiratory disease. It owes this popularity to a few factors: it is cheap, quick and simple to perform, delivers very little radiation, and is both familiar and acceptable to patients and clinicians. The basic method of acquiring a CXR has remained more or less the same over the past century. However, continuous refinements to image receptor technology have enabled CXRs to be acquired more efficiently.
