超声检查方法简便、无创伤,目前已成为临床诊断肝脏疾病的一种重要手段,但传统的二维超声主要是反射波和散射波成像,须依靠肉眼分析图像的回声强度,对灰阶变化的分辨力有限,评价的主观性较大,且只能定性,不能定量,准确性受到一定限制,因此需要一种可对正常和病变组织进行定量检
Ultrasound has the advantages of simple and non-invasive method and has become an important method for clinical diagnosis of liver diseases. However, the traditional two-dimensional ultrasound is mainly reflected wave and scattered wave imaging, and the echo intensity of the image needs to be analyzed by the naked eye. The resolution is limited, the evaluation of the subjectivity larger, and can only be qualitative, can not be quantified, the accuracy is subject to certain restrictions, so a need for a normal and diseased tissue quantitative test
