This disclosure relates to methods for non-destructively inspecting an object, wherein electromagnetic radiation is passed through the object and intensity values of unabsorbed beams are measured and evaluated. The method can include generating a three-dimensional data set in which a first material property of the object is associated with individual spatial elements of the object using computed tomography; determining an inspection space, in the three-dimensional data set; deriving values, based on the three-dimensional data set, corresponding to a spatial geometric quantity of the inspection space in a predetermined projection direction; generating a two-dimensional data set in which a second material property of the object is associated with individual surface elements of the object, using two-dimensional X-ray; determining an inspection region in the two-dimensional data set by computing a projection of the inspection space into the two-dimensional data set; and transferring the derived values into corresponding surface elements of the projection.

Method and X-ray inspection system, in particular for non-destructively inspecting objects

Among other things, one or more techniques and/or systems for selectively inhibiting radiation from being generated by a radiation source are provided. A radiation source comprises an electrically conductive gate situated between a cathode and an anode. When a voltage potential is created between the gate and the cathode, a flow of electrons between the cathode and the anode is mitigated, thus inhibiting radiation from being generated by the radiation source. When the voltage potential is removed or lessened, electrons may more freely flow between the cathode and the anode to generate radiation. In some embodiments, a calibration, such as a dark calibration, may be performed while the gate mitigates the flow of electrons. Moreover, in some embodiments, an accelerating voltage applied to the radiation source may be held substantially constant when radiation is generated as well as when radiation generation is inhibited.

Dynamic control of radiation emission

A method and apparatus is provided for detection of a particular material in an object, in particular in an item of luggage, by means of electromagnetic radiation in which the intensities of non-absorbed radiation from at least three radiation planes are measured and evaluated in associated detector apparatus, wherein an image is produced, initially from the intensities of the non-absorbed radiation, and then if single regions of low complexity are found which are characterized by approximately constant intensities, an estimation of the attenuation coefficient s performed and a material detection is carried out in the region according to an algorithm which calculates a three-dimensional reconstruction from different views.

A transport bin for an X-ray inspection system, comprising a identifying device rigidly connected to the bin, the identifying device having a bin-specific identifier, wherein the identifying device has a memory, in which an identification code that is unique worldwide, in particular a universally unique identifier (UUID), is stored in such a way that the identification code can be read out.

A method for the detection of a specific material in an object (), especially in a piece of luggage, using electromagnetic beams, whereby the intensities of non-absorbed beams from at least three beam planes () in corresponding detector arrays () are measured and evaluated, using the following steps according to the invention: 1. generating an at least two-dimensional picture of the object () from the measured intensity values; 2. selecting one of the spatial regions displayed in the picture as a basis of the value of a material value, which is determined from intensity measurements, for examination; 3. determining at least one spatial-geometric value in the region to the examined from positional data of a two-dimensional picture and from intensity values using a stored value of a specific, absorption-influenced value of a suspected material. 4. determining, in addition, the corresponding spatial-geometric value solely from three-dimensional geometric values, which are determined from measured intensity values; and 5. comparing, directly or indirectly, values of the spatial-geometric values determined in steps 3 and 4, or values derived therefrom, in order to determine if the suspected material is actually present.

Method and device for detecting a given material in an object using electromagnetic rays

In an inspection device for inspecting objects for explosives and other items prohibited for travel, particularly in carry-on baggage, a transport shaft ( ) where there is little space, has incorporated thereabout radiation sources ( ), which generate at least three beams (FX , FX , FX ) at which are directed at corresponding linear detectors ( ). This transport shaft ( ) is extended by incorporation of equipment or system components ( ) that are not part of the inspection system ( ), or by additional system components ( ) being integrated into a housing ( ) of the inspection device ( ), with a necessary radiation protection for the inspection device in compliance with radiation protection regulations being provided by a shielding ( ) placed on or around a piece of equipment or its system components ( ) already existing in the transport system ( ), ideally in front of the transport shaft ( ).

Inspection device

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.
