Abstract

An interactive, easy-to-use computer program has been developed to assess the quality of softcopy display by measuring the contrast sensitivity, spatial resolution and spatial uniformity at different backgrounds and object types. The program features random variation of the test object location, which minimizes the guessing error often associated with psychophysical measurements. It operates on a Microsoft Window/NT platform and is intended for routine quality assurance (QA) as well as for acceptance testing of PACS. The QA data obtained with this program can be plotted chronologically and centrally managed so as to detect trends in monitor deterioration. The principal motivation for developing this program was to provide an indirect yet sensitive and accurate measure of monitor characteristics with a minimum of specialized equipment.
