  • Publication number: 20080205590
    Abstract: In a binocular steroscopic scanning radiographic imaging method, X-rays emitted by the same radiation source are used. The X-rays pass through a double-slit collimator to form two X-ray beam sectors, which are symmetric or asymmetric and have an angle between them. The X-ray beam sectors, after penetrating through an object under detection, are received by the left and right detector array, respectively, then converted into electric signals to be inputted to the respective image acquisition systems, and received by a computer processing system for image processing and displaying. A system corresponding to the method comprises a radiation source, a beam controller, two mutually connected arms of detector arrays, image acquisition systems connected respectively to each of the detector arrays and a computer processing system.

  • Publication number: 20080165932
    Abstract: The present invention provides a vehicle-carried radiation inspection system having a simple structure with advantages of convenient operation, little scanning blind area and reliable safety performance. The system comprises a loading vehicle, a lifting device mounted to the loading vehicle and a radiation scanning inspection means fixedly mounted to the lifting device so as to ascend/descend together with the lifting device. The lifting device is configured to enable the lifting device and the radiation scanning inspection means as a whole to be apart from the ground by a predetermined safety distance when the loading vehicle is moving, and to enable the minimum distance therebetween during inspection to be less than the predetermined safety distance. According to the invention, the radiation scanning inspection means may be switched between higher and lower positions as required with the ascending/descending of its combination with the lifting device.

  • Publication number: 20080156992
    Abstract: 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.

  • Publication number: 20080159840
    Abstract: The present invention relates to a trailer system, and particularly to a self-driving trailer system for a radiation imaging inspection system and a method for inspecting a vehicle by radiation imaging of a vehicle through the trailer system. The self-driving trailer system comprises two trailers symmetrical in structure. Each of the trailers comprises a driving device, running wheels, a trailer body, a carrying device, a lift cylinder, a balance wheel, and two pairs of guide wheels. The driving device, the running wheels, and the balance wheel are coupled with the trailer body. The carrying device is coupled with the trailer body through the lift cylinder. A front carrying arm and a rear carrying arm can clamp front wheels of a vehicle under inspection, and move upwards and downwards by the lift cylinder.
