摘要： A vehicle mounted mobile container or vehicle inspection system, including: a radiation source, a movable vehicle for carrying the inspection system, and a detector arm rack which has a horizontal arm and a vertical arm, a first end of the horizontal arm is connected to the vehicle and a second end thereof is connected to an end of the vertical arm. The horizontal arm and the vertical arm are connected by a pivotal connecting device such that the vertical arm may pivot in a vertical plane, and the horizontal arm and the vertical arm may be retracted in a same horizontal plane. The novel arm rack construction may reduce the space occupied by it on top of the scanning vehicle after the arm rack is stowed so as to reduce the eight of the scanning vehicle under running condition.

摘要： Inspection devices and inspection methods are disclosed. The inspection method includes: performing X-ray scanning on an object being inspected so as to generate an image of the object being inspected; dividing the image of the object being inspected to determine at least one region of interest; detecting interaction between a cosmic ray and the region of interest to obtain a detection value; calculating a scattering characteristic value and/or an absorption characteristic value of the cosmic ray in the region of interest based on size information of the region of interest and the detection value; and discriminating a material attribute of the region of interest by means of the scattering characteristic value and/or the absorption characteristic value. With the above technical solutions, inspection accuracy and inspection efficiency may be improved.
