Embodiment Construction

[0034] Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

[0035] A device for X-ray scanning of vehicles according to a preferred embodiment is in figure 1 , figure 2 and image 3 is shown in , and includes an inlet 1 on which an X-ray radiation source 2 is mounted on one side. The X-ray source 2 comprises a collimator 3 for forming a fan-shaped X-ray beam 4 . A detector 5 is arranged opposite the source 2 for receiving radiation passing through the vehicle and for converting the received radiation into digital electrical signals. In the example shown, the vehicle through which the radiation passes is indicated with 6 . In this example, the detectors 5 are located on the vertical beam 7 and the top beam 8 of the inlet 1 . A speed measuring device 9 is also optionally included for measuring the speed of the vehicle 1 . In the example shown, the speed measuring devic...

Abstract

An apparatus for X-ray scanning of vehicles includes a pulsed X-ray source (2) generating X-rays. A collimator forms (3) a fan -shaped beam from the X-rays. A detector (5) detects the fan- shaped beam after it passes through a vehicle (6). A speed sensor (9) measures a speed of the vehicle passing through the apparatus and providing an electrical output corresponding to the speed. An image formation module converts an output of the detector into an image of the vehicle, based on the measured speed of the vehicle. The width of the fan- shaped beam is substantially similar to the width of the detector. The X-rays comprise primarily photons with energy between 2.5 and 9 MeV. A filter (19) is adjacent to the collimator for filtering out low energy X-ray photons. A vehicle presence sensor (10) can be used, whose output is used to turn the X-ray source on and off. An alignment platform (13, 17) can be used for aligning the fan -shaped beam with the detector. A frequency of the pulses is adjusted based on the speed of the vehicle. The X-ray source is turned off if the speed of the vehicle is below a predetermined threshold.

Description

technical field [0001] The present invention relates to X-ray inspection technology, and more particularly to systems and methods for high-energy X-ray inspection of loaded vehicles (containers or general cargo), and more particularly to applications at critical facilities, seaports and borders. Intersections efficiently screen cargo. Background technique [0002] A number of systems are known for radiation inspection of trucks and containers, most of these systems are generally based on the same principle, generally X-ray radiation by an X-ray source, using a collimator to form a fan-shaped X-ray beam aimed at the vehicle , scan the vehicle with this fan beam, and convert the detected radiation into a digital signal after the radiation passes through the vehicle, and then process the digital signal into an image for the operator to view. Such systems are usually designed with multiple goals in mind. [0003] Some X-ray inspection systems are adapted to a high degree of mo...
