【摘要】 目的 将图象变换技术与图象定量分析技术有选择地结合起来进行B超临床诊断,探讨对慢性迁延性肝炎的诊断价值。方法 对15幅正常人肝脏及15幅肝炎患者的肝脏的图像先经窗口灰阶变换后进行纹理参数分析,将其结果与单纯进行纹理分析的结果进行对比。结果 未经窗口变换的正常肝与肝炎肝的同一种参数的均值接近,均方差较大;经过窗口变换后它们均值的差异增大,均方差减小。结论 应用图像变换技术与定量分析相结合的方法使B超声像图对肝炎有明显的诊断价值。更多还原

【Abstract】 to estimate the feasibility in making the diagnosis of chronic hapatitis by emptying the technique of B scan images transforne and the texture analysis. Methods After gray level window transforming, 15 images of normal livers and 15 images of hepatitis livers were analyzed in their texture parameters, and the results were compared. Results The mean values of the same texture parameters among the normal livers wthout wndow transforming were close to that of hapitis livers, and the mean square deviations were relatively larger. But after window transforming, the means values became obviously different , and the mean square deviations became smaller. Conclusion The method of cooperating the technique of image transforming and the quantitative analysis is obviously valuable in the diagnosis of hapatitis with ultrasonic images.更多还原
