An apparatus is disclosed for examining containers and/or vehicles at an airport for impermissible contents, such as explosives, weapons, drugs, smuggled goods and the like. To improve the ability to identify such items in the article or vehicle under inspection, an image processor is provided having a computer to which the signals of the radiation detectors are supplied. The computer uses these signals to calculate a radiation silhouette of the articles. A memory is provided in which a reference image of the article is stored. A comparison circuit is supplied with the signals from the computer and from the memory, so that a differential image derived from the calculated radiation silhouette from the computer and from the reference image is displayed on a monitor, connected to the comparison circuit. Differences between the cureent image and the reference image can thereby be easily observed.

Apparatus for the transillumination of articles with a fan-shaped

An apparatus for inspecting containers or vehicles at airports for illegal contents, such as bombs, weapons, drugs or smuggled goods includes two x-ray generators and two line-shaped radiation detectors, a first of the radiation detectors receiving radiation from a fan beam of a first radiation generator, and the second radiation detector receiving radiation from a fan beam of a second radiation generator. The respective central rays of the fan beams are disposed substantially perpendicularly realtive to each other.

Apparatus for the transillumination of articles with fan-shaped radiation

An X-ray device for scanning objects moving on a conveyor path and for processing the detector signals acquired by the scan has a comparator for identifying faulty signals, the comparator being in a control chain for an image storage memory such that, in the event of a faulty detector signal, the contents of a memory row preceding the faulty detector signal are transferred into the memory row into which the faulty detector signal, if a correct signal, would have been stored. The system also includes a correction element for generating a reference signal at 100% radiation intensity in which the mean value of a number of measured signals is formed. The system also includes an element for reducing the amplitude of the useful signal during measurement in comparison to the amplitude allocated to a radiation intensity of 100%.

X-ray scanner & detector signal processing system

An x-ray scanner generates a fan-shaped x-ray beam through which an object to be inspected is moved and a detector line which generates signals corresponding to the radiation attenuated by the object. The processing electronics includes a comparator for recognizing faulty detector signals by means of which the roll-in of data ito the image memory is controllable such that, given a faulty detector signal, the transfer of the information into a memory line allocated to the detector is inhibited. The x-ray scanner also includes an allocator unit which omits predetermined detector channels for the purpose of geometric balancing. Given outage of a detector, its detector channel is omitted by the allocator unit, based on a signal from the comparator, instead of a prescribed detector channel.

X-ray scanner

Device for producing X-ray pictures of bodies

An X-ray scanner for examining objects moved through an X-ray beam on a conveyor has a detector array disposed at the opposite side of the conveyor from the X-ray source and a pulse generator connected to the motor which drives the conveyor for generating a pulse trail dependent on the speed of the motor, and hence on the speed of the conveyor. The pulse generator is connected to a scanner for the detector array and controls the scan rate dependent upon the conveyor speed. The conveyor speed is controlled such that the quotient of the scan rate and the conveying speed is maintained constant in order to hold the imaging scale constant.
