AIMS
Texture analysis (TA) is becoming an increasingly used tool in radiological research. Some papers have been published on its use in ultrasound (US), but the way in which the machine settings affect the features has not yet been fully explored. With this research, we analyze how the time gain compensation (TGC) influences the features of the gray-level matrices in the abdominal US setting.
SUBJECTS AND METHODS
We analyzed the images acquired from the hepatorenal acoustic window of a healthy 29-year-old volunteer acquired with different TGC settings. TA was carried out using the LifeX software.
RESULTS
Several both 1 and 2 order gray-level matrices features showed a strong correlation with TGC settings.
CONCLUSIONS
TGC settings must be accounted for when carrying out further TA studies.
目的
纹理分析（TA）在放射学研究中越来越成为一种常用工具。已经有一些关于其在超声（US）中应用的论文发表，但机器设置影响特征的方式尚未得到充分探索。通过本研究，我们分析时间增益补偿（TGC）如何影响腹部超声检查中灰度矩阵的特征。
对象与方法
我们分析了从一名29岁健康志愿者的肝肾声学窗口获取的、使用不同TGC设置采集的图像。使用LifeX软件进行纹理分析。
结果
几个一阶和二阶灰度矩阵特征均与TGC设置显示出强相关性。
结论
在进行进一步的纹理分析研究时，必须考虑TGC设置。
