In the diagnostic ultrasound community, the echographic B-scan texture is an important area of investigation since it can be analyzed to characterize the histologic state of internal tissues. In the present paper, a minicomputer based system was used to digitize B-mode images and to develop a method to measure their textural information. This method is based on the concept of local information content of spatial image proposed by Lowitz (1983, 1984). It first measures the local gray-level histogram in a small square window centered on each picture element (pixel) of a digitized B-mode image. The information derived from the local histograms is then used to characterize the tissues, to partition the B-mode image into homogeneous zones of texture, to estimate to what extent a tissue is different from another, to delimit the contours of a tissue and to measure its surface. The method is illustrated on the thyroid gland but it can be applied to the study of other organs.
在超声诊断领域，超声B扫描纹理是一个重要的研究方向，因为可以通过对其进行分析来表征内部组织的组织学状态。在本文中，一个基于小型计算机的系统被用于对B模式图像进行数字化处理，并开发一种测量其纹理信息的方法。该方法基于洛维茨（1983年、1984年）提出的空间图像局部信息含量的概念。它首先在以数字化B模式图像的每个像素为中心的小方形窗口中测量局部灰度直方图。然后，从局部直方图中获得的信息被用于表征组织、将B模式图像划分为纹理均匀的区域、估计一种组织与另一种组织的差异程度、划定组织的轮廓并测量其表面积。该方法在甲状腺上得到了验证，但也可应用于其他器官的研究。
