Abstract

Picture archiving and communication systems (PACS) use large numbers of video monitors distributed throughout a hospital to display images to physicians. While luminance transfer characteristics of monitors may be measured in some institutions, resolution and other image quality factors are frequently ignored, except in research settings. This work centered around developing a quality control tool and identifying a set of measurements with which to measure display image quality. The tool consisted of an EG&G gamma scientific telemicroscope on a translation table, controlled by a portable computer and positioned on a movable cart. With this tool, we were able to make highly accurate measurements on monitors at multiple locations in the hospital. We settled on measurements consisting of spatial resolution, luminance uniformity, and stability of the display function under different conditions. We concentrated on three pairs of high quality monitors, each pair used together in a clinical or research setting.
