Abstract: 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.

Abstract: Systems and methods of automatically generating synthetic X-ray scan data include generating scan data corresponding to a frame holding or supporting an object, wherein the frame and hence the object is manipulated, without manual intervention, to be positioned in a plurality of orientations in three dimensional space. Subsequently, X-ray scan data corresponding to the object is isolated and extracted from the X-ray scan data corresponding to the frame, the X-ray scan data corresponding to the object is adjusted and finally each of the adjusted X-ray scan data corresponding to the object is inserted into X-ray scan data of a cargo container in order to generate a plurality of X-ray scan data of the cargo container embedded with the object.

Abstract: A system for inspecting an object, includes: a source of X-ray radiation; a horizontal array of detectors, wherein the source and the array of detectors are positioned substantially on a first plane; a platform configured to rotate as well as translate in a vertical trajectory, wherein the platform is positioned on a second plane between the source and the array of detectors, and wherein the object is disposed on the platform; and a computing device configured to: cause the source to fire a substantially horizontal fan beam in a third plane, wherein the third plane is above a top of the object; acquire calibration data from the array of detectors while the third plane is above the top of the object; cause the platform to simultaneously rotate and raise the object vertically upwards; acquire scan data of the object; and generate a three dimensional scan image of the object.

Abstract: The present specification describes a system of acquiring spectral information from backscatter scan data acquired using a detector panel having an array of ‘m’ spatially distributed, independent detector assemblies or modules an array of ‘n’ filters positioned over the array of detector assemblies or modules. In some embodiments, m=n. From the acquired set of detector response measurements, an energy spectrum is mathematically reconstructed or calculated by formulating and solving the energy reconstruction problem as an inverse problem.

Abstract: The present specification relates to a method for enabling an operator to perform visual layer separation, the method including: retrieving at least one X-ray scan image from a memory in data communication with an inspection system, wherein the image comprises a first area of pixels representative of a target object obscured by a clutter object and a second area of pixels representative of the clutter object; receiving a selection of the pixels representative of the first area; receiving a selection of the pixels representative of the second area; determining if the selected second area meets a predefined quality threshold; if the selected second area meets the predefined quality threshold, generating a modified at least one X-ray image; and if the selected second area does not meet the predefined quality threshold, prompting the operator to select a different second area of pixels representative of the clutter object.
