In a facility for checking large-volume goods, in particular freight goods, with an X-ray source, which emits X-rays for irradiating the goods, and with a detector arrangement aligned with the X-ray source, the detectors of the detector arrangement are designed or arranged in such a way that detector rows are produced with two row limbs which abut one another at right angles on their longitudinal sides, of which one limb is aligned parallel to the movement direction of the goods being checked, and the other is aligned perpendicular to this in the direction of the X-ray source.

Facility for inspecting large-volume goods, in particular freight goods

A method for improving detail detectability in x-ray images is provided, whereby by means of an x-ray inspection device a positive x-ray image of an object is made, the x-ray image is subdivided into an object region and an empty region, and the empty region of the x-ray image is darkened.

X-ray inspection systems with enhanced brightness control

A method and device is provided for controlling a hand luggage and other objects carried by flight passengers during check-in, wherein the complexity of an object is determined in a first verifying device by automatic verification. Afterwards, supplementary verification steps are carried out according to the determined complexity.

Method and device for checking carry-on luggage and other carried objects

In order to check hand luggage and other objects carried by persons, control stations are needed, which have a control unit, in particular an X-ray checking unit, a conveyor which extends through the control unit, a depositing point which is arranged ahead of the conveyor, and a removal point which is arranged behind the conveyor, for the objects and having transport tubs which can be placed onto the conveyor. Small objects and items of clothing are placed in the transport tubs and conveyed through the control unit for checking. A return conveyor for the transport tubs is arranged next to or below the conveyor which passes through the control unit, which return conveyor reaches from the removal point behind the conveyor at least as far as into the region of the depositing point ahead of the conveyor.

A method of optimizing an X-ray image representing an article transilluminated by X-rays, includes the following steps: detecting the X-rays leaving the article after transillumination thereof by the X-rays; processing, in a computer, the detected X-rays as image dots to obtain an image; applying the image dots to an image memory; scanning the image dots according to gray scale values thereof; comparing the scanned gray scale values with a desired threshold gray scale value; upon finding an image dot which is other than the desired threshold gray scale value, counting subsequent image dots to obtain an image zone A; determining the gray scale values of the image dots of the image zone A; and expanding the gray scale values of the image dots of the image zone A to higher image dot values for effecting a local brightening of the X-ray image in the image zone A by the higher image dot values.

Method for the image optimization of an x-ray image

An image processing method for recognizing a material contained in an article includes the following steps: transilluminating the article with X-rays; generating, by an X-ray detector, signals representing the X-rays passing through the article; applying the signals to a computer system as continuous image data; subdividing the image data into defined zone-wise image strips; briefly storing the image strips in an image data memory; and determining the material from the image strips before a completion of the transilluminating step.
