Appropriate selection of a display subsystem requires balancing the optimization of its physical parameters with clinical setting and cost. Recent advances in Liquid Crystal Display (LCD) technology warrant a rigorous evaluation of both the specialized and the mass market displays for clinical radiology. This article outlines step two in the evaluation of a novel 9.2 million pixel IBM AMLCD panel. Prior to these experiments, the panel was calibrated according to the DICOM Part 14 standard, using both a gray-scale and a pseudo-gray scale lookup table. The specific aim of this study is to compare human, contrast-detail perception on different computer display subsystems. The subsystems that we looked at included 3- and 5-million pixel "medical-grade" monochrome LCDs and a 9.2-million pixel color LCD. We found that the observer response was similar for these three display configurations.
选择合适的显示子系统需要在优化其物理参数与临床环境及成本之间取得平衡。液晶显示器（LCD）技术的最新进展使得有必要对临床放射学的专业显示器和大众市场显示器进行严格评估。本文概述了对一款新型920万像素IBM有源矩阵液晶显示器（AMLCD）面板评估的第二步。在这些实验之前，该面板已根据DICOM第14部分标准进行校准，使用了灰度和伪灰度查找表。本研究的具体目的是比较在不同计算机显示子系统上人类对对比度细节的感知。我们研究的子系统包括300万像素和500万像素的“医疗级”单色LCD以及920万像素的彩色LCD。我们发现，观察者对这三种显示配置的反应相似。
