本文叙述了声像图的直方图形成原理及其分析方法。介绍了三种直方图取样方法,即:①点分析取样;②线分析取样;③面分析取样。描述了用以分析的谱线宽度、高次谱位、谱线包络线及统计数据等参数。 本法有助于鉴别各种液性、实质性、纤维化、钙化或结石及混合性病变。本法对超声诊断的量化分析具有十分重要的意义。 This article describes the principle of histogram formation of sonography and its analytical method. Three histogram sampling methods are introduced, namely: ① point analysis sampling; ② line analysis sampling; ③ surface analysis sampling. Describes the parameters used to analyze spectral line width, high spectral positions, spectral envelope, and statistical data. This law helps to identify a variety of liquid, substantial, fibrosis, calcification or stones and mixed lesions. The method of quantitative analysis of ultrasound diagnosis is of great significance.
