A BRIEF REVIEW OF HUMAN PERCEPTION FACTORS IN DIGITAL DISPLAYS FOR PICTURE ARCHIVING AND COMMUNICATIONS-SYSTEMS

The purpose of this review is to further inform radiologists, physicis ts, technologists, and engineers working with digital image display de vices of issues related to human perception. This article will briefly review the effects of several factors in human perception that are sp ecifically relevant to a digital display environment. These factors in clude the following: the spatial and contrast resolution of the displa y device; background luminance level and luminance range of the displa y system; brightness uniformity; extraneous light in the reading room; displayed field size; viewing distance; image motion and monitor flic kering; signal to noise ratio of the displayed image; magnification fu nctions; and the user interface. After reviewing the perception study results, a checklist of desirable features and quality assurance issue s for a digital display workstation are presented as an appendix.
