    • A method for improving the ability to recognize materials in an X-ray inspection system is provided that includes the steps of recording at least two absorption X-ray images of an object to be examined at different energies, mathematically modeling the object by a number of layers assuming a particular material for each layer, wherein an absorption value describes the absorptivity of a layer, the number of layers is less than or equal to the number of X-ray images and at least one layer is assumed to be a material to be recognized during the inspection, decomposing the absorption value of each layer into a path-dependent factor and an energy-dependent factor, calculating the path-dependent factors for all layers from the absorption X-ray images using the absorption equation, calculating at least one synthetic image from the sum of all layers of the product of the absorption values and the weighting factors, evaluating the synthetic image.
    • 提供了一种用于提高识别X射线检查系统中的材料的能力的方法,其包括以下步骤:以不同的能量记录待检测物体的至少两个吸收X射线图像,以数学方式对物体建模多个 假设每层具有特定材料的层,其中吸收值描述层的吸收率,层的数量小于或等于X射线图像的数量,并且至少一层被认为是材料 在检查期间识别,将每个层的吸收值分解成路径依赖因子和能量依赖因子,使用吸收方程从吸收X射线图像计算所有层的路径依赖因子,计算至少一个 从吸收值和加权因子的乘积的所有层的总和合成图像,评估合成图像。

    • A betatron is provided, particularly in an x-ray inspection station, comprising an accelerator block that is provided with a rotationally symmetrical inner yoke composed of two spaced-apart pieces, at least one main field coil, and a toroidal betatron tube which is disposed between the pieces of the inner yoke. The betatron further comprises an outer yoke which embraces the accelerator block, connects the two pieces of the inner yoke, and has at least one lateral opening, as well as a lead shield that accommodates the accelerator block and the outer yoke. The outer yoke is composed of at least two parts which are movable relative to one another between an open and a closed position. The accelerator block can be laterally removed from the opening of the outer yoke that is in the open position.
    • 特别是在x射线检查站中提供了一个贝塔管,包括一个加速器块,该加速器块设置有由两个间隔开的件组成的旋转对称的内轭架,至少一个主励磁线圈和一个设置在环形管的管形管 内轭之间。 贝塔管还包括外轭铁,其包围加速器块,连接两个内轭铁,并且具有至少一个侧向开口,以及容纳加速器块和外轭的铅屏蔽。 外轭铁由至少两部分构成,它们在打开和关闭位置之间可相对于彼此移动。 加速器块可以从处于打开位置的外轭的开口横向移除。
