Cassette based digital X-ray systems: evaluating the Konica Minolta Xpress CR

Cassette-based digital x-ray systems--also called computed radiography (CR) systems--are flexible and affordable, qualities that have secured their continued use in clinical settings. In this follow-up to our August 2001 Evaluation of CR systems, we examine the Konica Minolta Xpress CR. Our testing examines the ability of the Xpress CR to provide at least the same amount of diagnostic information as screen-film systems, while significantly increasing the overall efficiency of a radiology department. This article also includes updated information on the new products now offered by the suppliers whose CR systems we examined in August 2001. In addition, it describes the general developments that have occurred in CR technology. These developments include the use of new phosphor types to increase image quality and the wider implementation of wall-mounted touchscreens to improve workflow.
