This invention is directed towards finding, locating, and confirming threat items and substances. The inspection system is designed to detect objects that are made from, but not limited to, special nuclear materials (SNM) and/or high atomic number materials. The system employs advanced image processing techniques to analyze images of an object under inspection (OUI), which includes, but is not limited to baggage, parcels, vehicles and cargo, and fluorescence detection.

A method for positioning a target in a three-dimensional CT image and a security check system. The method includes: displaying a three-dimensional CT image; receiving a selection by a user of at least one area of the three-dimensional CT image at a first viewing angle to generate a first three-dimensional description; receiving a selection by the user of at least one area of the three-dimensional CT image at a second viewing angle to generate a second three-dimensional description, wherein an angle between the first viewing angle and the second viewing angle is within a predetermined range and the first three-dimensional description and the second three-dimensional description are related to a size, a location, and/or a physical property of a target at corresponding viewing angles; and determining the target in the three-dimensional CT image based on the first three-dimensional description and the second three-dimensional description.

An X-ray examination station includes a first source of X-ray radiation for whole body scanning of a human body using a first fan beam of X-ray radiation; a first vertical linear radiation detector configured to detect the first fan beam; a second source of X-ray radiation installed at mid-height of a person being examined, for scanning a central portion of the human body using a second fan beam of X-ray radiation; a second vertical detector of X-ray radiation configured to detect the second fan beam; and a control unit configured to turn on each of the X-ray radiation sources. The first and the second radiation fan beams are emitted in parallel planes. The first X-ray radiation source is turned on for the whole body scanning. The second X-ray radiation source is turned on for scanning the torso portion of the body.

An adjustable collimator device for collimating a beam of energy emitted from a radiation source is disclosed. The collimator has an elongated plate-like body with a front-end and a rear-end. The collimator has a first set of emission apertures equally spaced around a central axis of the body that defines a zero-degree position. The first set of emission apertures are placed on the rear-end of the body and are configured to receive and sample a beam of energy entering the adjustable collimator device. A second set of apertures are placed proximate the front-end of the body. The second set of apertures are adjustable such that a first of the second set of apertures can be configured to have a first angular offset relative to the zero-axis and a second of the second set of apertures can be configured to have a second angular offset relative to the zero-axis.

The present invention consists of a method and a scanning system for nonintrusive inspection, through radiography of inspected aircrafts from at least two different perspectives. The complete scanning system for nonintrusive inspection of aircrafts according to the invention is a mobile nonintrusive scanning ensemble, installed on a vehicle chassis with a superstructure, on which a deformable parallelogram profile and a mechanical boom are mounted with a penetrating radiation source at one end. A detector line assembly is installed on the ground. A hinged boom is fitted with an array of detectors and positioned opposite a relocatable radiation source. The scanning system for nonintrusive inspection include a mobile tugging device to tow the inspected aircraft at constant speed through the scanning frames. A mobile control center is placed outside the exclusion area a.

In some examples, there is described a method for processing inspection data associated with cargo irradiated by a plurality of successive pulses of X-rays. The method may involve obtaining the inspection data, the inspection data being generated as a result of scanning the cargo using a matrix including a plurality of at least two rows of detectors, and a source of the plurality of successive pulses. In some examples radiation corresponding to the plurality of successive pulses irradiating the cargo is arranged in a first order on the plurality of rows of detectors of the matrix and one or more successive reconstruction zones for the inspection data and corresponding to different orders are determined. Intermediate images of the cargo and an average image are generated. On the generated average image, pixels may be selected and neighbourhoods of the pixels having fewer artefacts may be extracted.

Scanner, including housing; first conveyor that transports luggage into housing; first plurality of sensors detects presence of luggage on first conveyor; second conveyor transports luggage through housing; second plurality of sensors detects presence of luggage on the second conveyor; pickup table for luggage pieces that do not require manual inspection; third conveyor that transports luggage to pickup table; first conveyor does not move luggage into housing as long as previous luggage was not sent to pickup table or until luggage taken from first conveyor; first X-ray source with first beam direction; second X-ray source with second beam direction, wherein first and second beam directions are 50-60 degrees apart; wherein first X-ray source has 100-160 KVolt on its anode; wherein second X-ray source has 100-160 KVolt on its anode; first detector detects first X-ray beam after luggage passes through beam; second detector detects second beam after luggage passes through beam.
