| 目的应用图像变换技术与图像定量分析技术有选择地结合起来进行B超临床诊断,探讨对急性肝炎的诊断价值。方法通过对25幅正常人肝脏及18幅急性肝炎的超声图像先进行窗口灰阶变换后进行纹理参数分析,将其结果与单纯地进行纹理分析的结果加以比较。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对急性肝炎声像图有明显的诊断价值。 |

| Purpose The techniques of image transform and texture analysis are cooperated selectively for clinic diagnosis of Bscan images,and the estimation of the diagnosis of acute hepatitis is investigated.Methods After Gray Level Window Transforming the 25 images of normal livers and 18 images of acute heptatitis are analyzed with texture parameter method,furthermore the results are compared with those obtained by only simple texture analysis.Results For the mean values of the same texture parameter the one of normal livers with no window transform is very close to the one of hepatitis livers,and they mean square deviation is relatively larger.But after window transforming they mean values become obviously different and they mean square deviations become smaller.Conclusion The method of cooperating the techniques of image transform and texture analysis is obviously valuable in clinic diagnosis for the ultrasonic images of hepatitis livers. |
