目的医用显示器供应商承诺使用10位或11位单色显示器比8位更有利诊断。用高灰度分辨率测量可得到的“最小可觉差”(JND)梯度,从影像质量的不同方面评估放射科医生的喜好。方法在一台显示器上用8、10和11位查找表(LUT)测JND梯度量。影像同时显示于8位和11位
Purpose The medical display supplier promises to use the 10-bit or 11-bit monochrome display for a more favorable diagnosis than the 8-bit. Radiologists’ preferences are assessed from different aspects of image quality by measuring the available “minimally perceptible difference” (JND) gradient with high grayscale resolution. Methods Measure the JND gradient with the 8, 10, and 11-bit look-up tables (LUTs) on a single display. Images are displayed in both 8 and 11 positions simultaneously
