摘要:
以数字射线实时成像技术为研究对象,对透照厚度、一次透照长度、动态范围和图像分辨率等方面进行了系统研究。结果表明:通过改变透照工艺参数,被检工件在探测器成像范围内均能清晰成像,仅需保留成像效果相对较好的区域,对其进行裁剪作为检测结果,且宜选用低电压、高电流以提高图像的清晰度;DR(digital radiography)技术的动态范围较高,但其检测图像的分辨率低于普通X射线底片,可通过软件改变图像的锐度,从而提高图像的清晰度。
Abstract:
With digital radiography real-time imaging technology as the research object, the transmission thickness, once-through penetration length, dynamic range and image resolution were systematically studied. The results showed that workpiece can clear imaging within the scope of the detector imaging by changing the transillumination process parameters, just need to keep the imaging effect better area to cut as the test results, suitable for use of low voltage and high current to improve image clarity; the dynamic range of DR technology is higher, and the image resolution of DR is lower than normal X-ray film, but its image sharpness can be changed by software to improve image clarity.
