射线检测 ,系统优化目的是能在检测过程中检测到尽可能小的疵病 ,因此 ,在对系统进行优化设计中 ,灵敏度是最重要的指标之一 ,也是我们最关心的参数 ,先对影响灵敏度的成像环节进行系统优化的讨论 ,并从透照电压、影像的降噪技术、补偿技术等方面进行优化研究 ,得出了一些有益的结论 . Ray detection, the purpose of system optimization is to detect the detection process as small flaws, therefore, the optimal design of the system, the sensitivity is one of the most important indicators, but also our most concerned about the parameters, the first impact Sensitivity of the imaging aspects of the system optimization discussion, and from the transillumination voltage, image noise reduction technology, compensation technology and other aspects of the optimization study, and reached some useful conclusions.
