摘要
Abstract
Application of the variogram for characterizing ultrasound image texture features was proposed in this paper to differentiate abnormal liver from normal liver. And the coefficient of anisotropy was also deifned to further characterize ultrasound image texture features. Four abnormal livers and ifve liver cancers were involved in this study using this method to calculate the r(h) max value and analyze each image from eight directions. The results showed that r(h) max value of normal livers was smaller and r(h) max value of liver cancers was bigger; while, the coefficient of anisotropy for normal livers was more and that of liver cancers was smaller. Hence, both the parameters r(h) max and coefifcient of anisotropy can be used to differentiate liver cancers from normal livers.关键词
