Control of luggage and shipped goods are frequently carried out. The possibilities of X-ray technology shall be demonstrated.
There are different imaging techniques. The main concepts are transmission imaging, backscatter imaging, computed tomography, and dual energy imaging and the combination of different methods The images come from manufacturers and personal collections.
The search concerns mainly, weapons, explosives, and drugs; furthermore animals, and stolen goods, Special problems offer the control of letters and the detection of Improvised Explosive Devices (IED).
One has to expect that controls will increase and that imaging with X-rays will have their part. Pattern recognition software will be used for analysis enforced by economy and by demand for higher efficiency - man and computer will produce more security than man alone.
对行李和运输货物的检查经常进行。应展示X射线技术的可能性。
存在不同的成像技术。主要概念包括透射成像、背散射成像、计算机断层扫描、双能成像以及不同方法的组合。图像来自制造商和个人收藏。
检查主要涉及武器、爆炸物和毒品；此外还有动物和被盗物品。信件检查和简易爆炸装置（IED）检测存在特殊问题。
必须预计到检查将会增加，并且X射线成像将发挥作用。模式识别软件将用于分析，这受到经济因素和对更高效率的需求的推动——人与计算机将比仅靠人产生更高的安全性。
