【摘要】：目的基于游程长度分析的超声有向性纹理定量测量方法和技术细节基本确定后,了解典型的超声有向性纹理的正常值范围和彼此间的差异,并了解目前确立的纹理测量方法在超声有向性纹理定量测量中的准确性。方法本研究分正常神经组、骨骼肌组、乳腺腺体组三组,各组对象分别在规定体位及仪器条件下取神经、骨骼肌、乳腺腺体超声图像,用自行研制的软件、以64×64像素点的正方形取样框对所取图像中最典型的有向性纹理进行取样,计算其游程长度纹理参数,用单因素方差分析三组参数测值的差异。结果三组的参数中大部分有显著差异,其中4个纵横比参数(参数9~12)在三组间不仅差异显著(P0.05),而且参数的大小与实验前的设想一致。结论基于游程长度分析的超声有向性纹理定量测量方法,不仅能够准确地测量各种超声有向性纹理,而且能够将不同长短粗细的超声有向性纹理区分开。
[Abstract]:Objective to determine the quantitative measurement method and technical details of ultrasonic directional texture based on run length analysis, and to understand the normal range of typical ultrasonic directional texture and the differences between them. And to understand the accuracy of the established texture measurement method in the quantitative measurement of ultrasound texture. Methods the study was divided into normal nerve group skeletal muscle group mammary gland group three groups. The ultrasound images of nerve, skeletal muscle and mammary gland were taken from each group under the specified position and instrument, and the software was developed by ourselves. The most typical directional texture of the image is sampled with a square sampling box of 64 脳 64 pixels, and the run-length texture parameters are calculated. Results most of the parameters of the three groups were significantly different, and four aspect ratio parameters (parameter 912) were not only significantly different among the three groups (P 0.05). Conclusion the quantitative measurement method of ultrasonic directional texture based on run-length analysis can not only accurately measure all kinds of ultrasonic directional texture. Moreover, the ultrasonic directional texture with different length and thickness can be distinguished.
