The possibility is exemplified of visualising important parameters of the statistical texture describing the echogenicity of ultrasound B-mode scans of the liver as a composite image. The two relevant parameters are gray level and standard deviation of gray levels. These were selected because they offer the best criterion to differentiate between tissues. In a composite image, the mean gray level is represented by the luminosity information, whereas the other main parameter of the gray-level histogram, the standard deviation of gray levels, is represented by the colour information. These composite images show texture parameters of the whole scan and allow an efficient documentation of the same.
将描述肝脏超声B模式扫描回声性的统计纹理的重要参数可视化为合成图像的可能性得到了例证。两个相关参数是灰度级和灰度级的标准差。选择它们是因为它们提供了区分组织的最佳标准。在合成图像中，平均灰度级由亮度信息表示，而灰度级直方图的另一个主要参数，即灰度级的标准差，由颜色信息表示。这些合成图像显示了整个扫描的纹理参数，并允许对其进行有效记录。
