In recent times, the security focus for civil aviation has shifted from hijacking in the 1980s, towards deliberate sabotage. X-ray imaging provides a major tool in checked baggage inspection, with various sensitive techniques being brought to bear in determining the form, and density of items within luggage as well as other material dependent parameters. This review first examines the various challenges to X-ray technology in securing a safe system of passenger transportation. An overview is then presented of the various conventional and less conventional approaches that are available to the airline industry, leading to developments in state-of-the-art imaging technology supported by enhanced machine and observer-based decision making principles.
近年来，民航安全重点已从20世纪80年代的劫机事件，转向蓄意破坏行为。X射线成像在托运行李检查中提供了一种主要工具，各种敏感技术被用于确定行李内物品的形状、密度以及其他与材料相关的参数。本综述首先考察了X射线技术在确保安全的客运系统方面面临的各种挑战。然后概述了航空业可采用的各种传统和非传统方法，这些方法推动了基于先进机器和基于观察者的决策原则的先进成像技术的发展。
