Paper Abstract

Image sources for the medical intensive care unit workstation used to view portable chest radiographs include both digitized screen-film images and phosphor plate images. This study compares usage of image manipulation functions when physicians view the images from different sources on the workstation. The authors hypothesize that the improved image-to- image uniformity afforded by phosphor plate radiography reduces the use of some of these functions; in particular, the controls for image brightness and contrast. The automated workstation logs and analysis of the results from digitized film-based and phosphor plate-based study periods show that this hypothesis is supported. Overall, use of all image manipulation functions decreased, but use of brightness/contrast showed the largest decrease, from 24.5% for digitized film to 7.6% for phosphor plate imaging. The overall workstation usage increased for the phosphor plate period, supporting the idea that this decrease in function usage was not the result of overall decrease in workstation use. This paper further describes the comparison of the workstation usage during these two study periods.
