摘要
针对数字射线检测技术平板探测器的检测工艺参数不同导致信噪比不同的问题,通过控制变量法依次改变各检测参数,以XRD 0822 AP14型平板探测器为对象,采集不同参数下的图像,对采集到的图像信噪比进行统计分析。结果表明,管电流、管电压、单帧曝光时间及积分次数均对信噪比有较大影响,而增益对信噪比几乎无影响。该试验结果可为获得更高信噪比的检测工艺制定提供参考。
In order to solve the problem of different signal-to-noise ratio caused by different detection process parameters of flat-panel detector in digital ray detection technology,the detection parameters were changed in turn,through the control variable method.Taking the XRD 0822 AP14 flat panel detector as the object,the images under different parameters were collected,and the signal-to-noise ratio of the collected images was statistically analyzed.The results show that the tube current,tube voltage,single frame exposure time and integration times had a great influence on the signal-to-noise ratio,while the gain had little effect on the signal-to-noise ratio.The experimental results can provide reference for the formulation of detection process to obtain better signal-to-noise ratio.
