尘肺X线胸片的计算机辅助诊断

A computer assisted diagnosis for pneumoconiosis X-ray film

用模拟和数字两种方法增强图象，以突出病灶，然后运用新颖的区域生长法识别、测量单个尘肺小阴影，通过统计运算进行尘肺病的诊断和分期。此种辅助诊断方法，提供信息直观可靠。３０例Ｘ线胸片密集度测定结果，与矽肺病期级别相一致。

After enhance the picture's definition at nidi by simulation technique and number system,the smallshad ow of Pneumoconiosis could be disbingaished and measured by the original regional growth method.Then Pneumoconiosis can be diagnosis and grade,after operating the statistics.This assisted diagnosis system is reliable and auto-visual.We had measured density of small rounded pneumoconiosis opacities in chest X-kay films of 30 patients.The results identify with silicosis category.
