SCANNING APPARATUS AND METHOD FOR THE DETECTION OF OBJECTS CONCEALED IN CARGO
In one embodiment, there is provided a detection device (1) for a system for inspection of cargo, comprising: at least one scintillator (4) configured to re-emit light in response to: interaction with successive first radiation pulses (5) emitted by a generator (6), and/or interaction with second radiation (5) generated by a radioactive source (8) located in the cargo (3) to inspect; at least one first acquisition line (9) configured to measure a quantity associated with the light re-emitted by the at least one scintillator in response to interaction with the successive first radiation pulses; and at least one a second acquisition line (10) configured to measure a quantity associated with the light re-emitted by the at least one scintillator in response to interaction with at least the second radiation.
Non-destructive X-ray inspection machine, devices provided for such machine and method for operating the same
Non-destructive X-ray inspection machine for individually packaged products having a bottom and a lid or cap in separate zones. The machine comprises a conveying apparatus having a transport plane adapted to convey products with the bottom resting on the transport plane, at least two X-ray emitters adapted to emit X-rays so that X-rays pass through the products at a top-to-down angle and at a down-to-top angle, respectively, in an inspection zone comprised in the transport plane. In the machine, at least one of the two emitters is freely adjustable in height and/or orientable in angle, within a predetermined range, relative to the transport plane, whereby the bottom of the product is inspectable without the X-rays of the two emitters intercepting the lid or cap of the products and optimal projection of the bottom of the product can be obtained.
Whole-Body Transmission X-Ray Scanner and Methods for Whole-Body Scanning
A whole-body transmission x-ray scanner includes a collimated x-ray source, a linear x-ray camera configured to detect x-rays, a counterweight, and a positioner that aligns the source and ray camera and moves the source and camera synchronously to scan and acquire radiographic images of an object located therebetween. The positioner comprises a cable alignment assembly connecting the counterweight directly to the x-ray source and camera to maintain alignment of the source and camera during a scanning mode in which the source and camera move from one end of the object to another end. The positioner comprises a motor, a bi-directional crossover slide track bearing assembly connected to the source, and a conveyor operatively connected to the motor and to the slide track bearing assembly to move the slide track bearing assembly in a loop that correspondingly translates the source and camera along a single linear axis.
Inspection devices and methods for inspecting a container
The present disclosure discloses an inspection device and a method for inspecting a container. Transmission scanning is performed on the inspected container using a scanning device including a sparse area array detector to obtain scan data. Digital focusing is performed at a specific depth position in a depth direction. Defocused pixel values are filtered out to obtain a slice image at the specific depth position. It is judged whether dangerous articles or suspicious articles are included in the slice image.
Method and system for a multi-view scanner
An X-ray inspection system for scanning objects is provided. The system includes a stationary X-ray source made of one or more linear modules positioned around a scanning volume, and defining sparsely positioned multiple stationary X-ray source points from which X-rays can be directed through the scanning volume. An X-ray detector array extends around the scanning volume and is arranged to detect X-rays from the source points which have passed through the scanning volume. A conveyor is arranged to convey the objects through the scanning volume and at least one processor processes the detected X-rays to produce three dimensional images of the items.
Distributed Analysis X-Ray Inspection Methods and Systems
The present specification discloses systems and methods for integrating manifest data for cargo and light vehicles with their X-ray images generated during scanning. Manifest data is automatically imported into the system for each shipment, and helps the security personnel to quickly determine the contents of cargo. In case of a mismatch between cargo contents shown by manifest data and the X-ray images, the cargo may be withheld for further inspection. In one embodiment, the process of analyzing the X-ray image of the cargo in conjunction with the manifest data is automated.

Scan method, scan system and radiation scan controller
This invention provides a scan method, scan system and radiation scan controller, and relates to the field of radiation. The scanning method includes obtaining detection data of an object to be inspected under radiation scanning using a detector, adjusting an accelerator output beam dose rate and/or an output electron beam energy level of a radiation emission device according to the detection data. With this method, working conditions of the accelerator of the radiation emission device may be adjusted according to the detection data detected by the detector, so that for a region having a larger mass thickness, a higher output beam dose rate or a higher electron beam output energy level is adopted to guarantee satisfied imaging technical indexes, for a region having a smaller mass thickness, a lower output beam dose rate or a lower electron beam output energy level is adopted to reduce the environmental dose level while guaranteeing satisfied imaging technical indexes.
X-ray detecting apparatus
An x-ray detecting apparatus having a housing, a detecting panel provided at an inside the housing as to detect x-rays, and a circuit board having a first surface thereof bordering with the detecting panel and a second surface thereof provided with at least one electronic component installed thereto is provided.
SYSTEM AND METHOD FOR FISSIONABLE MATERIAL DETECTION WITH A SHORT PULSE NEUTRON SOURCE
A system and method is disclosed for detecting fissionable materials. In one embodiment the system may incorporate a neutron pulse generator configured to generate multiple short pulses of neutrons, or a single pulse of sufficient intensity, in a vicinity of an object of interest. The source pulse of neutrons includes neutrons which each have a full width half maximum time duration of less than about 100 ns and a peak energy level no greater than about 20 MeV. A fast response detector is used which is able to detect single neutron events indicative of fission neutrons having been produced by the source pulse of neutrons interacting with fissionable material associated with the object of interest, and which arrive at the fast response detector within a predetermined time window immediately before arrival of the source neutron pulses.
