针对X射线成像GEM探测器
分析了3种基线值获取方法
给出零压缩阈值的最佳设定方法。测试结果表明
采用文中方法给出的零压缩阈值对数据进行零压缩可有效提高数据的有效利用率
从而提高探测器的计数率。在相同时间内
统计量大大提高
也有效改善了探测器的二维成像质量。
In R&D of a GEM detector for X-ray imaging
many methods of baseline acquisition and zero-suppression threshold setting have been studied.In this paper
by comparing the methods to measure baseline of GEM detector are compared
an appropriate method to obtain the zero compress thresholds is used for high count rate application of the GEM detector
with better statistics
which improves the quality of 2-D images.The method can be a general reference for other detectors.
