title: An added quality-control measurement for fluoroscopic x-ray systems.
abstract: Six fluoroscopic systems were evaluated to determine if improvements in imaging could be achieved. In four of the systems, improved contrast perceptibility could be obtained through adjustment and lowering of the image-intensifier input exposure rates (IIIER). The other two systems required no change or an increase in the IIIER.
