Four displays (pseudocolor mappings) available on a standard color TV are compared using two series of images (100 normal brains and 100 normal livers) with 50 computer-simulated lesions superimposed on each set. Four observers viewed the sets of images in such a way that the order of the display methods for both organs formed two orthogonal Latin squares. The observers were asked to locate and rate, on a standard scale, the most apparent area in each image, and ROC analysis was applied to the results. The "heated-object spectrum" was shown to be a useful display for brain images. It was also shown that the choice of display depends on the organ to be imaged.
使用两组图像（100个正常大脑和100个正常肝脏，每组叠加50个计算机模拟病变）比较了标准彩色电视上可用的四种显示方式（伪彩色映射）。四位观察者以这样的方式查看图像集：两个器官的显示方法顺序形成两个正交拉丁方。要求观察者在标准量表上定位并评估每个图像中最明显的区域，并将ROC分析应用于结果。结果表明，“热物体光谱”是一种对脑图像有用的显示方式。还表明，显示方式的选择取决于要成像的器官。
