    • The invention concerns a device for differentiating between organic and inorganic elements comprising a high energy photon source, a device for displacing objects to be inspected and an acquisition system consisting of a line of detectors designed to interact with the photons which have traversed through the object to be inspected. It comprises a filtering system (2) designed to interpose a filter between a high energy photon source (1) and the object to be inspected, a computer-aided device controlling and synchronising (5) the filtering (2) and the acquisition (4) systems and a display system (6), the computer-aided system (5) elaborating, on the basis of the signals of two measurements performed with different filters the atomic number Z of the material traversed in the different zones of the object (7) and producing an image of the object by attributing a code to said zones according to their organic or inorganic nature.
    • 本发明涉及一种用于区分有机和无机元件的装置,该装置包括高能量光子源,用于移动待检查物体的装置和由检测器线组成的采集系统,所述检测器线设计成与穿过物体的光子相互作用, 被检查。 它包括设计用于在高能光子源(1)和待检查对象之间插入滤波器的滤波系统(2),控制和同步(5)滤波(2)和采集(4)的计算机辅助设备 )系统和显示系统(6)中,计算机辅助系统(5)基于用不同过滤器执行的两次测量的信号来详细描述在物体(7)的不同区域中穿过的材料的原子序数Z ),并根据它们的有机或无机性质通过将代码分配给所述区域来产生物体的图像。
