关于线性数字层面图像质量改进的研究

A Study of Improving Digit Linear Tomography Image Quality

本文简述了层面技术的基本原理,然后报导消除层面上不必要的模糊图像的一种方法。这种方法使层面上所需的真正图像更为清晰。用计算机对这种方法进行了模拟。结果证明了这种方法的有效性。本文还作了连续物体采样分层的定量分析。结果表明:层的厚度与X射线源(简称源)扫描角成反比关系。也和物体本身线性衰减系数的特点有关。

The principle of Dynamic Linear Tomography has simply beendescribed. This paper substantially introduced a method which eliminates theblurring image and retains real image we need at the focal plane. It has beensimulated on the computer. We have made experiment using the phantom ofobject. It was in effect that the result of experiment showed, The quantitativeanalysis of sample quantom layer for continuing body is given. As the resultof experiment, the Tomographic Layer thickness is inversely proportional tothe angles of X-ray source travel, and it also is up to the feature of the lin-ear attenuation coefficient of body itself.
