To compare hard copies and soft copies processed with linear and nonlinear conversion of skeletal fractures, we performed a receiver-operating characteristics study of 25 digital radiographs. There was no statistical difference between hard copies with linear and nonlinear conversion. However, it may be difficult to detect small fractures on images processed by nonlinear conversion. No significant difference was seen between CRT diagnosis and that on a hard copy processed with linear conversion and frequency enhancement.
为比较经骨骼骨折线性和非线性转换处理的硬拷贝与软拷贝，我们对25张数字X线片进行了受试者操作特征研究。线性转换和非线性转换的硬拷贝之间无统计学差异。然而，在经非线性转换处理的图像上可能难以检测到小骨折。阴极射线管（CRT）诊断与经线性转换和频率增强处理的硬拷贝诊断之间未见显著差异。
