Abstract:
1. An inspection system for detecting a specific material of interest in an item of baggage, the inspection system comprising: a first scanner system for determining an attenuation coefficient of the item of baggage; a second scanner system for determining a diffraction pattern of the item of baggage; and a calculation unit connected to the first and second scanner systems for identifying a presence of the specific material of interest in the item of baggage on the basis of the attenuation coefficient and the diffraction pattern, wherein the first and second scanner systems are arranged at a distance from each other, wherein the first scanner system is a computed tomograph configured to apply a fan-shaped or cone-shaped radiation beam to the item of baggage; and wherein the second scanner system is a coherent-scatter computed tomograph configured to apply a fan shaped radiation beam to the item of baggage.
