The quantitative analysis of liver ultrasound images by depth correction

The attenuation in ultrasound is one of primary factor reducing quality of image. The heterogeneity intensity of ultrasound images was made by scatter and attenuation. In this study, the quantitative analysis of liver ultrasound images was performed by three extracted features with and without depth corrections. A tissue phantom and 136 empirical images were involved to evaluate the reliability and performance with three extracted features. The average intensity of ROI with depth correction had better reliability and performance with AUC 0.689 and specificity, sensitivity, and accuracy are 67%, 60%, and 62% with respectively.
