title: The evaluation of high-speed screen-film combinations in angiography.
abstract: Various high-speed screen-film combinations were evaluated to compare increase in speed, loss of resolution, and increase in radiographic mottle. Results indicate that the rare-earth film-screen system is the fastest and has a higher x-ray absorption efficiency. The Kodax X-Omatic screen has the greater resolving power but is slower than the high-speed calcium tungstate system. A smaller focal spot can be used with the fast speed of the rare-earth system to increase resolution.
