Abstract

A 600-speed system based on Ultra-Vision^TM technology has been designed. Since the undoped yttrium tantalate phosphore used in other Ultra-Vision^TM screens is incapable of achieving the required speed with existing films it was necessary to admix a small fraction of lanthanum oxybromide which is a more efficient x-ray to light converter and which emits both visible (approximately 470 nm) and UV (approximately 370 nm) light. The image quality performance of the resulting system approaches that of conventional 400-speed film/screen systems. These image quality characteristics are described and compared with those of conventional 600-speed and 400-speed systems.
