Paper Abstract

It has been well established that X-ray films are best read at high peak brightness (2000-4000 nits), yet current LCD and CRT displays used in radiology have peak brightness of only 500-700 nit typically. We have developed super-bright LCD displays that for the first time approach light box brightness levels while maintaining good viewing angle characteristics and uniformity. We provide characterization of a new monochrome model with 2000 nit peak brightness and a new color model with 500 nit peak brightness. To investigate the effect of the increased brightness on search performance, a small observer study was performed. Eight radiologists and residents were asked to search for low-contrast artefacts (15 mm ovals) superimposed on a mammogram. Four different LCD displays were used, with peak brightnesses from 200 to 2000 nit. For low-contrast artefacts, search performance was markedly improved at the highest brightness.
