Abstract

One of the promising methods of nondestructive testing for detecting substances that are similar in chemical composition and density is dual-energy X-ray image processing. In particular, dual-energy transformation algorithms can be applied to search for minerals hidden in waste rock. The method is most effective when the conditions for capturing X-ray images and energy levels are chosen correctly. This study compares the effectiveness of image processing using the dual-energy method in three cases of spectrum composition modification: first, by adjusting the voltage on the X-ray tube; second, by attenuating low-energy radiation using a copper filter; and third, by combining these methods. Fragments of beryl embedded in crushed muscovite were used as detection samples. A pulsed X-ray source that generates nanosecond-duration radiation pulses was used in this study. An original high-voltage generator circuit was implemented for the method of controlling radiation energy by varying the peak voltage on the X-ray tube. The use of such X-ray sources allows for obtaining high-resolution X-ray images of moving objects.

修改脉冲x射线源发射光谱的方法比较，以确定最有效的双能图像处理

双能x射线图像处理是一种很有前途的无损检测方法，用于检测化学成分和密度相似的物质。特别是，双能量转换算法可以用于搜索隐藏在废石中的矿物。当捕获x射线图像的条件和能级选择正确时，该方法是最有效的。本研究比较了双能法在三种光谱成分修改情况下的图像处理效果：第一种是通过调整x射线管上的电压；第二，利用铜滤波器衰减低能辐射；第三，结合这些方法。以白云母破碎包埋的绿柱石碎片为检测样品。在这项研究中使用了一种脉冲x射线源，产生纳秒持续时间的辐射脉冲。为实现通过改变x射线管上的峰值电压来控制辐射能量的方法，设计了一种新颖的高压发生器电路。使用这种x射线源可以获得运动物体的高分辨率x射线图像。

期刊介绍： Russian Journal of Nondestructive Testing, a translation of Defectoskopiya, is a publication of the Russian Academy of Sciences. This publication offers current Russian research on the theory and technology of nondestructive testing of materials and components. It describes laboratory and industrial investigations of devices and instrumentation and provides reviews of new equipment developed for series manufacture. Articles cover all physical methods of nondestructive testing, including magnetic and electrical; ultrasonic; X-ray and Y-ray; capillary; liquid (color luminescence), and radio (for materials of low conductivity).
