| 摘 要： | 目的 通过计算机辅助诊断的方法对食管微小病变进行快速实时筛查.方法 利用计算机图像处理技术捕捉食管微小病变区域的灰度变化,通过色调(H)、饱和度(S)区域均数比较算法和灰度的波动频率积分算法对采集到的食管图像进行实时、快速处理.结果 基于上述两种算法研制的食管图像处理软件对食管的各种病变,包括正常食管粘膜、食管炎、早期食管癌、中晚期食管癌、食管粘膜不典型增生等都有辅助诊断的价值.结论 基于本算法研制的软件可作为临床诊断食管微小病变的一种有效的辅助手段.

| Abstract: | Objective To investigate the effect of computer-assisted real-time diagnosis on esophagus micro-focused lesion based on the change of grey shade. Methods Comparison algorithm for the hue saturation mean value and integral algorithm for the vibration frequency of grey color shade were used to analyze the esophagus images collected by quick and real-time operation. Results The research results showed that, the image-operative software, based on the two kinds of arithmetic mentioned above, had some effects on discriminating the esophagus micro-focused lesions, such as esophagitis, early carcinoma of esophagus, middle-late carcinoma of esophagus and atypical hyperplasia of esophagus one another. Conclusion The software could be used as a kind of assisted diagnostic measure to screen out the micro-focused lesion of esophagus effectively. |
