摘要:
The present invention discloses a mobile cantilever door-type container inspection system, in the art of radiation scanning imaging inspection technology. The system according to the present invention comprises a moveable scanning apparatus formed by a scanning frame and a remote control device, wherein the scanning frame comprises a radiation source and some detectors, wherein the radiation source or an apparatus cabin wherein the radiation source is disposed is connected with an L-shaped cantilever structure to form a door-type scanning frame, wherein beneath the radiation source or the apparatus cabin wherein the radiation source is disposed are provided with rollers that can reciprocatingly move on rails and are controlled by drive means. The detectors are disposed in a cross beam and a vertical beam of the cantilever structure of the door-type scanning frame. Rays of the radiation source are right in alignment with rows of detectors in the cantilever structure. The container truck to be inspected can pass through the door-like frame formed by the door-type scanning frame. Due to the cantilever structure, the inspection system is advantageous in stable operation, good-quality images, and high reliability.

The present invention provides a method and system of material identification using binocular steroscopic and multi-energy transmission image. With the method, any obstacle that dominates the ray absorption can be peeled off from the objects that overlap in the direction of a ray beam. The object that is unobvious due to a relatively small amount of ray absorption will thus stand out, and the material property of the object, such as organic, mixture, metal and the like can be identified. This method lays a fundament for automatic identification of harmful objects, such as explosive, drugs, etc., concealed in a freight container.

A method and a system for contraband detection in an object using photoneutrons and x-rays includes an x-ray generator that generates an x-ray main beam including a first x-ray beam and a second x-ray beam, the first x-ray beam being directed to pass through the object. A photoneutron conversion target is arranged to receive the second x-ray beam so as to generate photoneutrons, the photoneutrons being directed to enter the object and react with the object to emit characteristic γ-rays. An x-ray detecting arrangement is arranged to receive the first x-ray beam that has passed through the object in order to perform x-ray imaging detection of the detected object. A γ-ray detecting arrangement is arranged to receive the characteristic γ-rays in order to perform neutron detection of the object based on the characteristic γ-rays. The x-ray imaging detection and the neutron detection are simultaneously performed.

A radiation inspection system is disclosed. The radiation inspection system comprises: an inspection passage through which a moving object under inspection can pass, a radiation source disposed on a side of the inspection passage for emitting radiation, an array of detectors disposed on the other side of the inspection passage opposite to the radiation source for receiving the radiation emitted from the radiation source, a detector for detecting the moving object, and a controller for receiving a signal from the detector and controlling the radiation source to emit radiation when the detector detects the moving object for radiation imaging and inspection of the moving object. According to the radiation inspection system, the controller can control the radiation source to automatically emit radiation beam based on the detection signal from the detector for inspecting the moving object. As a result, inspection efficiency is improved, safety is increased, and misoperation of the radiation source is eliminated.
