| 摘 要： | X射线技术是一种成熟且应用非常广泛的安检技术,主要包括X射线透射法、双能X射线法、X射线背散射法和计算机断层扫描法等。其成像原理虽略有不同,但都是利用X射线与物质作用来提取物品的物理特征,从而达到安全检查的目的。在实际应用中,各类X射线技术都存在各自的缺点和不足,造成实际安检存在漏报、误报等问题,为解决这些问题,综合应用各类技术可能是一个有效的解决办法。

| Abstract: | X-ray technolo spection,mainly include X-ray transillumination,dual e puted tomography and so on. Although the principles of dif ent ways,all the methods extract physical characteristics of ials in order to achieve security inspection.All the method ing to misinformation and missing report in security inspection.Maybe integrating several methods is effective means. gy is one of matured technique and widely used in security in nergy scanning technique,back scattering,com ferent imaging technique have slightly differ materials using the action between X-ray and the mater s of X-ray have the shortcoming and defect in the application,lead |
