摘要: 在现有的安检技术中,X光CT技术是比较成熟、有效的手段之一。第一代X光CT安检机存在着较高的误报及漏报,CT技术的发展可以有效地解决这一问题。X光CT安检机与普通X射线安检机相比,有很多优点,技术有了本质上的提高,尤其是实现了三维成像和能够测定物体密度及原子序数,有效解决了普通X射线安检机成像的重影问题,能够自动与危险品的物理特征进行比对,减少人为因素的影响,既减轻安检人员的劳动强度,又能保证安检效果。Abstract: Among the various technologies of safety inspection,CT technique has become one of effective technologies.The first generation X-ray CT has high radio of wrong alarm and missing alarm.The new development has solved this problem.Comparing with X-ray security inspector,CT's security inspector have many advantages,because it is fundamental improvement.The fundamental improvement is three-dimensional imaging and determining density and the atomic number,overcoming the problem-double image of the X-ray security inspector.This techology can accomplish comparing physical characteristics with dangerous materials automaticly,reducing influence from human beings.The result is to lighten labor intensity of secruity staffs,also to guarantee the effect of security check.With the terrorism creeping all round the world,there is a large market for CT's security inspector.
